NCP300, NCP301 Voltage Detector Series The NCP300 and NCP301 series are second generation ultra-low current voltage detectors. These devices are specifically designed for use as reset controllers in portable microprocessor based systems where extended battery life is paramount. Each series features a highly accurate undervoltage detector with hysteresis which prevents erratic system reset operation as the comparator threshold is crossed. The NCP300 series consists of complementary output devices that are available with either an active high or active low reset output. The NCP301 series has an open drain N-Channel output with either an active high or active low reset output. The NCP300 and NCP301 device series are available in the Thin TSOP-5 package with standard undervoltage thresholds. Additional thresholds that range from 0.9 V to 4.9 V in 100 mV steps can be manufactured. http://onsemi.com MARKING DIAGRAM 5 5 1 xxx A Y W G Features * * * * * * * Quiescent Current of 0.5 mA Typical High Accuracy Undervoltage Threshold of 2.0% Wide Operating Voltage Range of 0.8 V to 10 V Complementary or Open Drain Reset Output Active Low or Active High Reset Output Specified Over the -40C to +125C Temperature Range (Except for Voltage Options from 0.9 to 1.1 V) Pb-Free Packages are Available (Note:Microdot may be in either location) PIN CONNECTIONS Reset Output 1 Input 2 Ground 3 5 N.C. 4 N.C.

Figures 20 and 21 show a timing diagram and a typical application. Initially consider that input voltage Vin is at a nominal level and it is greater than the voltage detector upper threshold (VDET+), and the reset output (Pin 1) will be in the high state for active low devices, or in the low state for active high devices. If there is a power interruption and Vin becomes significantly deficient, it will fall below the lower detector threshold (VDET-). This sequence of events causes the Reset output to be in the low state for active low devices, or in the Input Voltage, Pin 2 Reset Output (Active Low), Pin 1 high state for active high devices. After completion of the power interruption, Vin will again return to its nominal level and become greater than the VDET+. The voltage detector has built-in hysteresis to prevent erratic reset operation as the comparator threshold is crossed. Although these device series are specifically designed for use as reset controllers in portable microprocessor based systems, they offer a cost-effective solution in numerous applications where precise voltage monitoring is required. Figure 26 through Figure 33 shows various application examples. Vin VDET+ VDET- Vin VDET+ VDET- 0V Reset Output (Active High), Pin 1 Vin VDET+ VDET- 0V Figure 21. Timing Waveforms http://onsemi.com 14 NCP300, NCP301 VCC TRANSIENT REJECTION The NCP300 and NCP301 series provides accurate VCC monitoring and reset timing during power-up, power-down, and brownout/sag conditions, and rejects negative glitches on the power supply line. Figure 22 shows the maximum transient duration vs. maximum negative excursion (overdrive) for glitch rejection. Any combination of duration and overdrive which lies under the curve will not generate a reset signal. A below-VCC condition (on the right) is detected as a brownout or power-down. Typically, any transient that goes 100 mV below the reset threshold and lasts 5.0 ms or less will not cause a reset pulse. Transient immunity can be improved by adding a capacitor in close proximity to the VCC pin of the NCP30x. FACTORS TO BE CONSIDERED FOR VOLTAGE OPTION SELECTION The following hysteresis graph depicts VDET-_min/max and VDET+_min/max for an active low Reset device: Output VDET-_typ VDET-_min Overdrive Figure 24. For selecting a voltage option in the NCP30X family, three major factors should be considered: 1. VDET+_max: Maximum detector threshold voltage for increasing Vin for the NCP30X device. 2. Vin_min: Minimum voltage output of the power supply. This is also the input voltage to the NCP30X device. 3. VCC_min: Minimum power supply voltage specification for the device that is protected by the NCP30X. The VDET+_max for an NCP30X device is normally calculated as follows: Duration Figure 22. Max Transient Duration vs. Max Overdrive 300 TRANSIENT DURATION 250 200 VTH = 4.90 V VTH = 3.10 V V DET+_max + V DET-_max ) V HYS_max VTH = 1.60 V 30 50 70 90 110 130 RESET COMPARATOR OVERDRIVE (eq. 1) Where: VDET-_max = Maximum detector threshold voltage for decreasing Vin VHYS_max = Maximum detector threshold hysteresis The above two parameters can be obtained directly from the data sheet to figure out the VDET+_max. In the NCP30X family, for a given VDET-_typ, which is the typical detection voltage reflected in the part number, the threshold values are designed to the following targets (at 25C): 50 0 10 VDET+_max VDET+_min = VDET-_min + VHYS_min VDET+_max = VDET-_max + VHYS_max VTH 100 VDET+_min Input VCC 150 VDET-_max 150 Figure 23. V DET-_min + V DET-_typ * 2% (eq. 2) V DET-_max + V DET-_typ ) 2% (eq. 3) V HYS_typ + 5% of V DET-_typ (eq. 4) V HYS_min + V HYS_typ * 40% (eq. 5) V HYS_max + V HYS_typ ) 40% (eq. 6) By simple mathematical calculation, Equations 2 to 6, Equation 1 becomes: V DET+_max + V DET-_typ http://onsemi.com 15 1.09 combining (eq. 7) NCP300, NCP301 PROPAGATION DELAY VARIATION On the other hand (see above paragraph), a minimum overdrive value from Vthreshold to VCC must be respected. That means Vin (minimum value of VCC) must be higher enough than VDET+ (VDET- + hysteresis) at the risk of significantly increasing propagation delay. (Figure 25) This propagation delay is temperature sensitive. To avoid acceptable time response, a minimum 100 mV difference between Vin and VDET+ must be selected. So, VDET+_max can be easily figured out just using a single variable VDET-_typ. For example, for NCP300LSN18T1G VDET-_typ = 1.8 V; then V DET+_max + 1.8 1.09 + 1.962 V (eq. 8) The NCP30X detection voltage option must be chosen such that: V CC_min t V DET+_max t V in_min (eq. 9) The significance of VCC_min < VDET+_max is that it makes sure the the reset from NCP30X remains asserted (in RESET hold state) till after the power supply exceeds the VCC_min requirement; this prevents incorrect device (uP) initiation. Having VDET+_max < Vin_min makes sure that the NCP30X is able to start up when Vin is at the Vin_min. The theoretical ideal VDET-_typ voltage option to be selected by the user, VDET-_typ_ideal, can be given by the following formula: V DET-_typ_ideal + (2 600 500 TIME DELAY (ms) Vin_min ) VCC_min VDET+ (eq. 10) 1.09) 400 300 tpHL 200 tpLH 100 The following example shows how to select the device voltage option in a real world application. 1. Power supply output specification: 3.3 V $3% 2. Microprocessor core voltage specification: 3.3 V $5% So, we have: V in_min + 3.3 V * 3% + 3.201 V (eq. 11) V CC_min + 3.3 V * 5% + 3.135 V (eq. 12) 0 3.0 3.168 3.5 4.0 4.5 5.0 Vin, PULSE HIGH INPUT VOLTAGE (V) Figure 25. tpLH and tpHL vs. Input Voltage for the NCP301SNT1 Then the ideal voltage option = (3.201 + 3.135) / (2 * 1.09) = 2.9064 V Therefore, a device voltage option of 2.9 V will be the right choice. http://onsemi.com 16 5.5 NCP300, NCP301 APPLICATION CIRCUIT INFORMATION VDD 2 NCP300 Series 3 VDD * Input 1 Reset Reset Output Microprocessor * Required for GND GND NCP301 Figure 26.

When the input voltage falls outside of the window established by the upper and lower device thresholds, the LED will turn on indicating a fault. As the input voltage falls within the window, increasing from 1.0 V and exceeding the active low device's hysteresis threshold, or decreasing from the peak towards 1.0 V and falling below the active high device's undervoltage threshold, the LED will turn off.
