The SGM824A is a complete microprocessor supervisory device which combines reset and watchdog functions in a SOT-23-5 package. System reliability is significantly improved by such integration compared to the designs with individual ICs or discrete components. The SGM824A also features an excellent transient immunity to ignore fast VCC transients.
The device has an active-low reset output (nRESET) that is activated by a watchdog expiry event or due to a low VCC voltage. The nRESET output is guaranteed to be in the correct logic state even if VCC falls down to 1V. The device also has a complementary active-high reset output (RESET). The SGM824A is offered in three fixed VCC reset threshold voltages.
The SGM824A is available in a Green SOT-23-5 package. It operates over an ambient temperature range of -40℃ to +125℃.
