Product Summary
The ADM708SARZ is a microprocessor supervisory circuit. The ADM708SARZ is suitable for monitoring 5 V power supplies/batteries and can also monitor microprocessor activity. The ADM705/ADM706 provide power-supply monitoring circuitry that generate a reset output during power-up, power- down, and brownout conditions. The reset output remains operational with VCC as low as 1 V. Independent watchdog monitoring circuitry is also provided. The ADM708SARZ is is activated if the watchdog input has not been toggled within 1.60 seconds.
