  • Product Description

    The UM813 is cost effective system power supply supervisory circuit designed to monitor the power supplies in digital systems.

    The UM813 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 to monitor an additional power supply. An active low debounced manual reset input is also included.

    The UM813xS is the same as the UM706xS, except RESET is provided instead of /RESET.

    The UM813xS series are available in a small outline SOP8 package.
