SGM823 Datasheet | SG Micro

DESCRIPTION The SGM823 is a plete microprocessor supervisory device which bines reset, watchdog and manual reset functions in a SOT-23-5 package. System reliability is significantly improved by such integration pared to the designs with individual ICs or discrete ponents. The SGM823 also features an excellent transient immunity to ignore fast VCC transients. This device has an active-low push-pull reset output (n RESET) that is activated by a logic low on the manual reset input (n MR), a watchdog expiry event or due to a low VCC voltage. The n RESET 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 +125℃.
