NanoPower Supervisory & Watchdog Timer

Analog Devices NanoPower Supervisory & Watchdog Timer is used to monitor a single system supply voltage and the integrity of code execution by a microprocessor or microcontroller. The device asserts the reset output whenever the V_CC supply voltage is greater than the minimum operating voltage but less than the reset threshold. After the supply voltage rises above the reset threshold, the reset output remains asserted for the reset timeout period. It then deasserts. Reset voltage thresholds are available from 1.50V to 5.0V in approximately 100mV increments.
