UWD708 Datasheet






The UTC UWD708 microprocessor supervisory circuit reduces

the complexity and number of components required to monitor

power-supply and monitor microprocessor activity. It significantly

improves system reliability and accuracy compared to separate ICs

or discrete components.

The UTC UWD708 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.

In addition, there is a 1.25V threshold detector for power-fail

warning, low-battery detection, or monitoring an additional power

supply. An active-low manual-reset input ( MR ) is also included.




* Precision supply- Voltage Monitor

* Valid RESET remains with VCC as low as 1V

* 200ms Reset Pulse Width

* Voltage Monitor for Power-Fail or Low-Battery Warning

* With Manual reset input
