Input and output capacitors (CIN, CL) The S-19500/19501 Series requires CL between the VOUT pin and the VSS pin for phase compensation. Operation is stabilized by a ceramic capacitor with an output capacitance of 2.2 F or more over the entire temperature range. When using an OS capacitor, a tantalum capacitor, or an aluminum electrolytic capacitor, the capacitance must be 2.2 F or more, and the ESR must be 10 or less. The values of output overshoot and undershoot, which are transient response characteristics, vary depending on the value of the output capacitor. The required value of capacitance for the input capacitor differs depending on the application. Caution Define the capacitance of C IN and C L by sufficient evaluation including the temperature characteristics under the actual usage conditions. 2. Release delay time and monitoring time adjustment capacitor (CDLY) In the S-19500/19501 Series, the release delay time and monitoring time adjustment capacitor (CDLY) is necessary between the DLY pin and the VSS pin to adjust the release delay time (trd) of the detector and the monitoring time of the watchdog timer. The set release delay time (trd(S)), the set watchdog trigger time (tWI,tr(S)), the set watchdog output "L" time (tWD,L(S)) and the set watchdog output pulse period (tWD,p(S)) are calculated by using following equations, respectively. The release delay time (trd), the watchdog trigger time (tWI,tr), the watchdog output "L" time (tWD,L) and the watchdog output pulse period (tWD,p) at the time of the condition of CDLY = 47 nF are shown in " Electrical Characteristics".

The above equations will not guarantee successful operation. Perform thorough evaluation including the temperature characteristics using an actual application to set the constants. Mounted board layout should be made in such a way that no current flows into or flows from the DLY pin since the impedance of the DLY pin is high, otherwise correct delay time and monitoring time may not be provided. Select CDLY whose leakage current can be ignored against the built-in constant current (5.0 A typ.). The leakage current may cause deviation in delay time and monitoring time. When the leakage current is larger than the built-in constant current, no release takes place. Deviations of CDLY are not included in the equations mentioned above. Be sure to determine the constants considering the deviation of CDLY to be used. 17 AUTOMOTIVE, 125C OPERATION, 36 V INPUT, 200 mA, BUILT-IN WATCHDOG TIMER VOLTAGE REGULATOR WITH RESET FUNCTION S-19500/19501 Series Rev.1.7_00 3. Watchdog activation threshold current adjustment resistor (RWADJ,ext) In the S-19500/19501 Series, the watchdog activation threshold current adjustment resistor (RWADJ,ext) can be connected between the WADJ pin and the VSS pin to adjust the watchdog timer activation threshold current. The set watchdog activation threshold current (IO,WDact(S)), the set watchdog deactivation threshold current (IO,WDdeact(S)) and the set watchdog activation hysteresis current (IO,WDhys(s)) are calculated by using following equations, respectively.

Regulator block 1. 1 Basic operation Figure 32 shows the block diagram of the regulator in the S-19500/19501 Series. The error amplifier compares the reference voltage (Vref) with feedback voltage (Vfb), which is the output voltage resistance-divided by feedback resistors (Rs and Rf). It supplies the gate voltage necessary to maintain the constant output voltage which is not influenced by the input voltage and temperature change, to the output transistor.

Parasitic diode Figure 32 1. 2 Output transistor In the S-19500/19501 Series, a low on-resistance P-channel MOS FET is used as the output transistor. Be sure that VOUT does not exceed VIN + 0.3 V to prevent the voltage regulator from being damaged due to reverse current flowing from the VOUT pin through a parasitic diode to the VIN pin, when the potential of VOUT became higher than VIN. 19 AUTOMOTIVE, 125C OPERATION, 36 V INPUT, 200 mA, BUILT-IN WATCHDOG TIMER VOLTAGE REGULATOR WITH RESET FUNCTION S-19500/19501 Series Rev.1.7_00 1. 3 Overcurrent protection circuit The S-19500/19501 Series includes an overcurrent protection circuit which having the characteristics shown in "1. 1 Output voltage vs. Output current (When load current increases) (Ta = +25C)" of "1. Regulator block" in " Characteristics (Typical Data)", in order to limit an excessive output current and overcurrent of the output transistor due to short-circuiting between the VOUT pin and the VSS pin. The current when the output pin is short-circuited (Ishort) is internally set at 60 mA typ., and the load current when short-circuiting is limited based on this value. The output voltage restarts regulating if the output transistor is released from overcurrent status. Caution This overcurrent protection circuit does not work as for thermal protection. If this IC long keeps short circuiting, pay attention to the conditions of input voltage and load current so that, under the usage conditions including short circuit, the loss of the IC will not exceed power dissipation. 1. 4 Thermal shutdown circuit The S-19500/19501 Series has a thermal shutdown circuit to limit self-heating. When the junction temperature rises to 170C typ., the thermal shutdown circuit operates to stop regulating. After that, when the junction temperature drops to 135C typ., the thermal shutdown circuit is released to restart regulating. Due to self-heating of the S-19500/19501 Series, if the thermal shutdown circuit starts operating, it stops regulating so that the output voltage drops. For this reason, self-heating is limited and the IC's temperature drops. When the temperature drops, the thermal shutdown circuit is released to restart regulating, thus self-heating is generated again due to rising of the output voltage. Repeating this procedure makes the waveform of the VOUT pin output into a pulse-like form. This phenomenon continues unless decreasing either or both of the input voltage and the output current in order to reduce the internal power consumption, or decreasing the ambient temperature. Note that the product may suffer physical damage such as deterioration if the above phenomenon occurs continuously.

Detector block 2. 1 Basic operation (1) When the output voltage (VOUT) of the regulator is release voltage (+VDET) of the detector or higher, the Nch transistor (N1 and N2) are turned off and "H" is output to the RO pin. Since the Pch transistor (P1) is turned on, RB * VOUT the input voltage to the comparator (C1) is . RA + RB (2) Even if VOUT decreases to +VDET or lower, "H" is output to the RO pin when VOUT is the detection voltage (-VDET) or higher. When VOUT decreases to -VDET (point A in Figure 34) or lower, N1 which is controlled by C1 is turned on, and CDLY is discharged. If the DLY pin voltage (VDLY) decreases to the lower reset timing threshold voltage (VDRL) or lower, N2 of output stage of C2 is turned on, and then "L" is output to the RO pin. At this time, P1 is RB * VOUT turned off, and the input voltage to C1 is . RA + RB + RC (3) If VOUT further decreases to the IC's minimum operation voltage or lower, the RO pin output is "H". (4) When VOUT increases to the IC's minimum operation voltage or higher, "L" is output to the RO pin. Moreover, even if VOUT exceeds -VDET, the output is "L" when VOUT is lower than +VDET. (5) When VOUT increases to +VDET (point B in Figure 34) or higher, N1 is turned off and CDLY is charged. N2 is turned off if VDLY increases to the upper timing threshold voltage (VDU) or higher, and "H" is output to the RO pin.

The release delay time (trd) changes according to CDLY. Refer to "2. Release delay time and monitoring time adjustment capacitor (CDLY)" in " Selection of External Parts" for details. In addition, if the time from when VOUT decreases to -VDET or lower to when VOUT increases to +VDET or higher is significantly shorter compared to the length of the reset reaction time (trr), VDLY may not decrease to VDRL or lower. In that case, "H" output remains in the RO pin. Refer to "2. 9 Reset reaction time vs. Release delay time and monitoring time adjustment capacitance" in " Characteristics (Typical Data)" for the details. Caution Since trd depends on the charge time of CDLY, trd may be shorter than the set value if the charge operation is initiated under the condition that a residual electric charge is left in CDLY. 2. 3 Output circuit Since the RO pin has a built-in resistor to pull up to the VOUT pin internally, the RO pin can output a signal without an external pull-up resistor Do not connect to the pin other than VOUT pin when connecting an external pull-up resistor. In the S-19500 Series, the reset output pin and the watchdog output pin are prepared as the WO / RO pin. The output level of the WO / RO pin is applied by the AND logic of the reset output pin and the watchdog output pin. Example: When the WO pin is "L" and the RO pin is "H", the WO / RO pin is "L". In the S-19501 Series, the reset output pin is prepared as the RO pin.

Watchdog timer block 3. 1 Basic operation The watchdog timer operates as follows during monitoring operation. (1) When the WO pin outputs "H", CDLY is discharged by an internal constant current source, and the DLY pin voltage (VDLY) decreases. The watchdog timer detects a trigger and the CDLY is charged by an internal constant current source if a rising edge is input to the WI pin from a monitored object by the watchdog timer, and then VDLY rises. The discharge operation is restarted if VDLY reaches the upper timing threshold voltage (VDU), and VDLY decreases again. By inputting a rising edge to the WI pin again during the discharge operation, the similar operation is repeated. At this time, the WO pin outputs "H" continuously. (2) The watchdog timer does not detect a trigger if the rising edge is not input to the WI pin from a monitored object by the watchdog timer when the CDLY is discharged and VDLY decreases. The WO pin outputs "L" if the discharge operation continues not detecting a trigger when VDLY reaches the lower watchdog timing threshold voltage (VDWL). This operation is called the time-out detection. (3) After the time-out detection, CDLY is charged while the WO pin outputs "L", and VDLY increases. The WO pin outputs "H" and restarts the discharge operation if VDLY reaches VDU. (4) By the operation of (3), a monitored object by the watchdog timer is reset. If a rising edge is input to the WI pin again, the operation similar to (1) is continued since the watchdog timer detects a trigger. (5) After the operation of (3), if the status in which a rising edge is not input to the WI pin continues, the watchdog timer repeats the operation of (5) (3) (5) ...

Even if watchdog timer detects a trigger of signal input to the WI pin, the WO pin outputs "L" when VDLY reaches VDWL. After that, the watchdog timer restarts the monitoring operation if the WO pin outputs "H" when VDLY reaches VDU. 3. 2 Autonomous watchdog operation function (Output current detection circuit) Since the S-19500/19501 Series has a built-in output current detection circuit, the watchdog timer operates autonomously. When using the autonomous watchdog operation function, the current flows in the load is detected by the output current of the regulator, the watchdog timer initiates the activation when the output current is the watchdog activation threshold current (IO,WDact) or more, the watchdog timer is deactivated when the output current is the watchdog deactivation threshold current (IO,WDdeact) or less. Table 17 shows the connection of WADJ pin depending on the usage of the watchdog timer. In the S-19500 Series, the watchdog timer is deactivated regardless of the connection of the WADJ pin if the watchdog timer is set to Disable by the WEN pin. Usage of Watchdog Timer Watchdog timer is not in use Watchdog timer is always activated Watchdog timer turns on and off autonomously depending on the load current (Autonomous watchdog operation function) *1. *2. 24 Table 17 Connection of WADJ Pin Connect to the VSS pin Connect to the VOUT pin via a 270 k (recommended) resistor*1 Open or connect to the VSS pin via an external resistor*2 Status of WADJ Pin "L" "H" "H": IOUT > IO,WDact "L": IOUT < IO,WDdeact Even if the WADJ pin is directly connected to the VOUT pin, the watchdog timer is always activated. Note that the current consumption will increase by as many resistors as unconnected. Refer to "3. Watchdog activation threshold current adjustment resistor (RWADJ,ext)" in " Selection of External Parts" for details. AUTOMOTIVE, 125C OPERATION, 36 V INPUT, 200 mA, BUILT-IN WATCHDOG TIMER VOLTAGE REGULATOR WITH RESET FUNCTION Rev.1.7_00 S-19500/19501 Series Depending on the output current (IOUT) of the regulator, the watchdog timer monitoring activation is as follows. (1) When IOUT of the regulator is the watchdog activation threshold current (IO,WDact) or more, the WADJ pin voltage (VWADJ) is higher than the reference voltage (Vref), and the output of the comparator (C1) is "H". At this time, the watchdog timer initiates the monitoring activation. (2) When IOUT decreases to the watchdog deactivation threshold current (IO,WDdeact) (point A in Figure 38) or less, VWADJ decreases to Vref or less and the output of C1 is "L". At this time, the watchdog timer deactivates the monitoring. Even if IOUT increases, the watchdog timer continues the monitoring deactivation when IOUT is within less than IO,WDact (3) If IOUT further increases to IO,WDact (point B in Figure 38) or more, VWADJ increases to Vref or higher and the output of C1 is "H". And then, the watchdog timer initiates the monitoring activation.

Therefore, the WADJ pin voltage (VWADJ) may fluctuate since the current flowing through RWADJ,ext and RWADJ,int also changes in the same way if the output current changes transiently. VWADJ at that time should be evaluated with the actual device. Remark I O,WDact , I O,WDdeact and I O,WDhys can be adjusted by connecting R WADJ,ext to the WADJ pin. Refer to "3. Watchdog activation threshold current adjustment resistor (RWADJ,ext)" in " Selection of External Parts" for the detail. 25 AUTOMOTIVE, 125C OPERATION, 36 V INPUT, 200 mA, BUILT-IN WATCHDOG TIMER VOLTAGE REGULATOR WITH RESET FUNCTION S-19500/19501 Series Rev.1.7_00 3. 3 Watchdog enable circuit (only S-19500 Series) When inputting "L" to the WEN pin, the watchdog timer becomes Disable and stops the output current detection operation and monitoring activation. When inputting "H" to the WEN pin, the watchdog timer becomes Enable. The watchdog timer monitoring activation is performed depending on the connection of the WADJ pin. The WEN pin is pulled down internally by the constant current source. For this reason, the WEN pin is set to "L" when using the WEN pin in the floating status, and the watchdog timer becomes Disable. However, in order that the watchdog timer become Disable certainly, connect the WEN pin to GND so that "L" is input to the WEN pin certainly, since the impedance of the WEN pin becomes high when using the WEN pin in the floating status. In order to fix the watchdog timer to Enable, connect the WEN pin to the VOUT pin so that "H" is input to the WEN pin. Table 18 and Table 19 show the relation between each pin status and the watchdog timer. 3. 4 Watchdog input circuit By inputting a rising edge to the WI pin, the watchdog timer detects a trigger. The S-19500/19501 Series has a built-in watchdog input circuit which contains a band pass filter in the WI pin, and detects a rising edge which satisfies an input condition as a trigger signal. Refer to *2 of Table 10 and Figure 4 in " Recommended Operation Conditions". During the operation of the watchdog timer, a trigger is detected only when the DLY pin voltage is in VDU to VDWL and while the discharge operation of C DLY is being performed. Refer to "3. Watchdog timer block" in " Operation" for details. The signal input from a monitored object by the watchdog timer to the watchdog timer should be input with a time interval which is sufficiently shorter than the watchdog trigger time (tWI,tr). Table 18 and Table 19 show the relation between each pin status and the watchdog timer. Caution 3. 5 Under a noisy environment, the watchdog input circuit may detect the noise as a trigger signal. Sufficiently evaluate with the actual application to confirm that a trigger is detected only in the intended signal. Watchdog output circuit Since the WO pin has a built-in resistor to pull up to the VOUT pin internally, the WO pin can output a signal without an external pull-up resistor Do not connect to the pin other than VOUT pin when connecting an external pull-up resistor. In the S-19500 Series, the reset output pin and the watchdog output pin are prepared as the WO / RO pin. The output level of the WO / RO pin is applied by the AND logic of the reset output pin and the watchdog output pin. Example: When the WO pin is "L" and the RO pin is "H", the WO / RO pin is "L". 26 AUTOMOTIVE, 125C OPERATION, 36 V INPUT, 200 mA, BUILT-IN WATCHDOG TIMER VOLTAGE REGULATOR WITH RESET FUNCTION Rev.1.7_00 S-19500/19501 Series 3. 6 Each pin status and output logic Table 18 and Table 19 show each pin status and output logic in truth table. 3. 6. 1 S-19500 Series (Product with WEN pin) Status WDT monitoring activation WDT abnormal detection WDT monitoring deactivation WDT Disable Low voltage detection WEN Input "H" "H" "H" "L" Don't care Table 18 Each Pin Status WADJ WI Input Status*1 "H" "H" "L" Don't care Don't care Trigger No trigger Don't care Don't care Don't care VOUT Output +VDET +VDET +VDET +VDET -VDET Output Logic WO / RO Output "H" "L" "H" "H" "L" *1.

When mounting an output capacitor between the VOUT pin and the VSS pin (CL) and an input capacitor between the VIN pin and the VSS pin (CIN), the distance from the capacitors to these pins should be as short as possible. * Note that generally the output voltage may increase when a series regulator is used at low load current (0.1 mA or less). * Note that generally the output voltage may increase due to the leakage current from an output transistor when a series regulator is used at high temperature. * Generally a series regulator may cause oscillation, depending on the selection of external parts. The following conditions are recommended for the S-19500/19501 Series. However, be sure to perform sufficient evaluation under the actual usage conditions for selection, including evaluation of temperature characteristics. Refer to "4. Example of equivalent series resistance vs. Output current characteristics (Ta = -40C to +125C)" in " Reference Data" for the equivalent series resistance (RESR) of the output capacitor. Input capacitor (CIN): Output capacitor (CL): 2.2 F or more 2.2 F or more * In a series regulator, generally the values of overshoot and undershoot in the output voltage vary depending on the variation factors of power-on, power supply fluctuation and load fluctuation, or output capacitance. Determine the conditions of the output capacitor after sufficiently evaluating the temperature characteristics of overshoot or undershoot in the output voltage with the actual device. * The voltage regulator may oscillate when the impedance of the power supply is high and the input capacitance is small or an input capacitor is not connected. * Overshoot may occur in the output voltage momentarily if the voltage is rapidly raised at power-on or when the power supply fluctuates. Sufficiently evaluate the output voltage at that time with the actual device. * If the VOUT pin is steeply shorted with GND, a negative voltage exceeding the absolute maximum ratings may occur to the VOUT pin due to resonance of the wiring inductance and the output capacitance in the application. The negative voltage can be limited by inserting a protection diode between the VOUT pin and the VSS pin or inserting a series resistor to the output capacitor. * The application conditions for the input voltage, the output voltage, and the load current should not exceed the power dissipation. * Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic protection circuit. * In determining the output current, attention should be paid to the output current value specified in Table 11 in " Electrical Characteristics" and footnote *7 of the table. * ABLIC Inc. claims no responsibility for any disputes arising out of or in connection with any infringement by products including this IC of patents owned by a third party. 31 AUTOMOTIVE, 125C OPERATION, 36 V INPUT, 200 mA, BUILT-IN WATCHDOG TIMER VOLTAGE REGULATOR WITH RESET FUNCTION S-19500/19501 Series Rev.1.7_00 Characteristics (Typical Data) 1.
