The UM825 is cost effective system power supply supervisory circuit designed to monitor the power supplies in digital systems. The device provides circuit initialization and timing supervision. Manual reset input are included. The device significantly improves system reliability and accuracy compared to separate ICs or discrete components.
The UM825 is specifically designed to ignore fast transients on VCC. Seven preprogrammed reset threshold voltages are available. The device has an active-low reset output, which is guaranteed to be in the correct state for VCC down to 1V. The UM825 also offers a manual reset input and a complementary active-high reset.
