Microprocessor Supervisory Circuit with Watchdog Timer

The SGM824 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 SGM824 also features an excellent transient immunity to ignore fast VCC transients.

This device has an active-low push-pull reset output (nRESET) that is activated by a watchdog expiry event or due to a low VCC voltage. The nRESET output can still be in the correct logic state even if VCC is lower than 1V. The SGM824 is offered in four fixed VCC reset threshold voltages.

The SGM824 is available in a Green SOT-23-5 package. It operates over an ambient temperature range of -40 to +125.
