Overview
The UM823/824/825 series are cost effective system power supply supervisory circuits designed to monitor the power supplies in digital systems. This family provides circuit initialization and timing supervision. Independent watchdog monitoring circuitry and manual reset input are included. They significantly improve system reliability and accuracy compared to separate ICs or discrete components. The UM823/824/825 are specifically designed to ignore fast transients on VCC. Seven preprogrammed reset threshold voltages are available. All three devices have an active-low reset output, which is guaranteed to be in the correct state for VCC down to 1V. The UM823 also offers a watchdog input and manual reset input. The UM824 offers a watchdog input and a complementary active-high reset. The UM825 offers a manual reset input and a complementary active-high reset.
