Microprocessor Supervisory Circuit with Watchdog Timer and Manual Reset

The SGM823A is a complete microprocessor supervisory device which combines reset, watchdog and manual reset 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 SGM823A also features an excellent transient immunity to ignore fast VCC transients.

This device has an active-low reset output (nRESET) that is activated by a logic low on the manual reset input (nMR), 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 SGM823A is offered in three fixed VCC reset threshold voltages.

The SGM823A is available in a Green SOT-23-5 package. It operates over an ambient temperature range of -40 to +125.
