SGM817xQ
自動車グレードMicroprocessor Supervisory Circuit with Watchdog Timer and Manual Reset for Automotive Applications
The SGM817xQ 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 SGM817xQ 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 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 SGM817xQ is offered in four fixed VCC reset threshold voltages.
The device is AEC-Q100 qualified (Automotive Electronics Council (AEC) standard Q100 Grade 1) and it is suitable for automotive applications.
The SGM817xQ is available in a Green SOT-23-5 package. It operates over an ambient temperature range of -40℃ to +125℃.
