UM708RS - Union Semiconductor

UM708RS Supply Voltage Supervisor w/Watchdog Input and Manual Reset

The UM706xS/UM708xS/UM813xS series are cost effective system power supply supervisory circuits designed to monitor the power supplies in digital systems. The UM706xS provides power-supply monitoring circuitry that generates a reset output during power-up, power-down, and brownout conditions. The reset output remains operational with VCC as low as 1V.
