The SGM823 microprocessor (μP) supervisory circuit combines reset output, watchdog, and manual reset input functions in SOT-23-5 package. It significantly improves system reliability and accuracy compared to separate ICs or discrete components. The SGM823 is specifically designed to ignore fast transients on VCC.
Four preprogrammed reset threshold voltages are available. This device has an active-low reset output, which is guaranteed to be in the correct state for VCC down to 1V. The SGM823 also offers a watchdog input and manual reset input.
The SGM823 is available in a Green SOT-23-5 package. It operates over an ambient temperature range of -40℃ to +125℃.
