The SGM824 microprocessor (μP) supervisory circuit combines reset output, watchdog input functions in SOT-23-5 package. It significantly improves system reliability and accuracy compared to separate ICs or discrete components. The SGM824 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 SGM824 offers a watchdog input and a complementary active-high reset.
The SGM824 is available in a Green SOT-23-5 package. It operates over an ambient temperature range of -40℃ to +125℃.
