SGM823 - 5-Pin Microprocessor Supervisory

General Description

The SGM823 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.

Key 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 logic low on the manual reset input (nMR), 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 1V. The SGM823 is offered in four fixed VCC reset threshold voltages. The SGM823 is available in a Green SOT-23-5 package. It operates over a junction temperature range of -40℃ to +12.
