Supervisors

AEC-Q1003.3 V supervisorExtended watchdogVSON-8

TPS3851G33EQDRBRQ1 monitors a 3.3 V automotive rail and adds an extended-timing programmable watchdog with separate RESET and WDO outputs.

Best for

  • Automotive 3.3 V rail supervision
  • Microcontroller watchdog monitoring

Avoid if

  • A push-pull reset output is required
  • The system cannot provide external output pullups

Check before use

  • Worst-case undervoltage threshold
  • CWD capacitor tolerance
  • WDI service interval
