DESCRIPTION

The UTC UWD706 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 UWD706 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. Independent watchdog monitoring circuitry is also provided. This is activated if the watchdog input has not been toggled within 1.6 seconds.

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.

FEATURES

* Precision supply- Voltage Monitor

* Valid RESET remains with VCC as low as 1V

* 200ms Reset Pulse Width

* Independent Watchdog Timer (1.6sec) Timeout

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

* With Manual reset input
