Key Specifications

The UM706xS/UM706xM8/UM708xS/UM813xS series are cost effective system power supply supervisory circuits designed to monitor the power supplies in digital systems.

The UM706xS/UM706xM8 provides power-supply monitoring circuitry that generates a reset output during power-up, power-down, and brownout conditions. The reset output remains operational with V_CC 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 UM708xS is the same as the UM706xS, except an active-high reset is substituted for the watchdog timer. The UM813xS is the same as the UM706xS, except RESET is provided instead of RESET_______________.
The UM706xS, UM708xS, UM813xS are available in a small outline SOP8 package.The UM706xM8  is available in a small outline SOP8 package.
