APPLICATIONS Microprocessor systems Computers Controllers Intelligent instruments Portable equipment GENERAL DESCRIPTION The ADM823/ADM824/ADM825 are supervisory circuits that monitor power supply voltage levels and code execution integrity in microprocessor-based systems. In addition to providing power-on reset signals, an on-chip watchdog timer can reset the microprocessor if it fails to strobe within a preset timeout period. A reset signal can also be asserted by an external pushbutton, through a manual reset input. The three parts feature different combinations of watchdog input, manual reset input, and output stage configuration, as shown in Table 1. These parts are available in a choice of seven reset threshold options ranging from 2.19 V to 4.63 V. The reset and watchdog timeout periods are fixed at 140 ms (minimum) and 1.6 sec (typical), respectively. The ADM823/ADM824/ADM825 are available in 5-lead SC70 and SOT-23 packages and typically consume only 5 A, making them suitable for use in low power, portable applications. Table 1.

Watchdog Input Minimum Pulse Width vs. Temperature (ADM823/ADM824) ADM823/ADM824/ADM825 CIRCUIT DESCRIPTION RESET OUTPUT The ADM823 features an active low, push-pull reset output, and the ADM824/ADM825 feature dual active low and active high push-pull reset outputs. For active low and active high outputs, the reset signal is guaranteed to be logic low and logic high, respectively, for VCC 1 V. The reset output is asserted when VCC is below the reset threshold (VTH), when MR is driven low, or when WDI is not serviced within the watchdog timeout period (tWD). Reset remains asserted for the duration of the reset active timeout period (tRP) after VCC rises above the reset threshold, after MR transitions from low to high, or after the watchdog timer times out. Figure 15 illustrates the behavior of the reset outputs. VCC VCC The ADM823/ADM825 feature a manual reset input (MR) which, when driven low, asserts the reset output. When MR transitions from low to high, reset remains asserted for the duration of the reset active timeout period before deasserting. The MR input has a 52 k internal pull-up so that the input is always high when unconnected. An external push-button switch can be connected between MR and ground so that the user can generate a reset. Debounce circuitry for this purpose is integrated on chip. Noise immunity is provided on the MR input and fast, negative-going transients of up to 100 ns (typical) are ignored. A 0.1 F capacitor between MR and ground provides additional noise immunity. WATCHDOG INPUT The ADM823/ADM824 feature a watchdog timer that monitors microprocessor activity. A timer circuit is cleared with every low-to-high or high-to-low logic transition on the watchdog input pin (WDI), which detects pulses as short as 50 ns. If the timer counts through the preset watchdog timeout period (tWD), reset is asserted. The microprocessor is required to toggle the WDI pin to avoid being reset. Failure of the microprocessor to toggle WDI within the timeout period, therefore, indicates a code execution error, and the reset pulse generated restarts the microprocessor in a known state. In addition to logic transitions on WDI, the watchdog timer is also cleared by a reset assertion due to an undervoltage condition on VCC or by MR being pulled low. When reset is asserted, the watchdog timer is cleared and does not begin counting again until reset is deasserted. The watchdog timer can be disabled by leaving WDI floating or by three-stating the WDI driver.

Reset Timing Diagram Rev. B | Page 9 of 12 tRD 04534-021 The ADM823/ADM824/ADM825 provide microprocessor supply voltage supervision by controlling the reset input of the microprocessor. Code execution errors are avoided during power-up, power-down, and brownout conditions by asserting a reset signal when the supply voltage is below a preset threshold. Errors are also avoided by allowing supply voltage stabilization with a fixed timeout reset pulse after the supply voltage rises above the threshold. In addition, problems with microprocessor code execution can be monitored and corrected with a watchdog timer (ADM823/ADM824). By including watchdog strobe instructions in microprocessor code, a watchdog timer can detect whether the microprocessor code breaks down or becomes stuck in an infinite loop. If this happens, the watchdog timer asserts a reset pulse that restarts the microprocessor in a known state. If the user detects a problem with the system's operation, a manual reset input is available (ADM823/ADM825) to reset the microprocessor with an external push-button, for example. ADM823/ADM824/ADM825 APPLICATIONS INFORMATION WATCHDOG INPUT CURRENT WATCHDOG SOFTWARE CONSIDERATIONS To minimize the watchdog input current (and minimize overall power consumption), leave WDI low for the majority of the watchdog timeout period. When driven high, WDI can draw as much as 160 A. Pulsing WDI low-high-low at a low duty cycle reduces the effect of the large input current. When WDI is unconnected, a window comparator disconnects the watchdog timer from the reset output circuitry so that reset is not asserted when the watchdog timer times out. In implementing the microprocessor watchdog strobe code, quickly switching WDI low-to-high and then high-to-low (minimizing WDI high time) is desirable for current consumption reasons. However, a more effective way of using the watchdog function can be considered. To avoid unnecessary resets caused by fast power supply transients, the ADM823/ADM824/ADM825 are equipped with glitch rejection circuitry. The typical performance characteristic in Figure 12 plots VCC transient duration vs. the transient magnitude. The curves show combinations of transient magnitude and duration for which a reset is not generated for 4.63 V and 2.93 V reset threshold parts. For example, with the 2.93 V threshold, a transient that goes 100 mV below the threshold and lasts 8 s typically does not cause a reset, but if the transient is any larger in magnitude or duration, a reset is generated. An optional 0.1 F bypass capacitor mounted close to VCC provides additional glitch rejection. ENSURING RESET VALID TO VCC = 0 V Both active low and active high reset outputs are guaranteed to be valid for VCC as low as 1 V. However, by using an external resistor with push-pull configured reset outputs, valid outputs for VCC as low as 0 V are possible. For an active low reset output, a resistor connected between RESET and ground pulls the output low when it is unable to sink current. For an active high reset output, a resistor connected between RESET and VCC pulls the output high when it is unable to source current. A large resistance such as 100 k should be used so that the reset output is not overloaded when VCC is above 1 V. START SET WDI HIGH PROGRAM CODE INFINITE LOOP: WATCHDOG TIMES OUT SUBROUTINE SET WDI LOW RETURN Figure 18. Watchdog Flow Diagram VCC VCC RESET 04534-020 NEGATIVE-GOING VCC TRANSIENTS A low-high-low WDI pulse within a given subroutine prevents the watchdog timing out. However, if the subroutine becomes stuck in an infinite loop, the watchdog cannot detect this condition because the subroutine continues to toggle WDI. A more effective coding scheme for detecting this error involves using a slightly longer watchdog timeout. In the program that calls the subroutine, WDI is set high (see Figure 18). The subroutine sets WDI low when it is called. If the program executes without error, WDI is toggled high and low with every loop of the program. If the subroutine enters an infinite loop, WDI is kept low, the watchdog times out, and the microprocessor is reset.
