TPS3851H33EQDRBRQ1 is a TI automotive voltage supervisor for nominal 3.3 V rails, combining a -7% undervoltage monitor with an extended-timing programmable watchdog.

Best for

  • Automotive 3.3 V microcontroller supervision
  • Systems requiring a separate watchdog fault output
  • Low-current power monitoring

Avoid if

  • A different monitored voltage or adjustable voltage threshold is required
  • A push-pull reset output is required
  • The watchdog timing must be independent of capacitor tolerance

Check before use

  • Verify the -7% nominal threshold against the minimum allowable 3.3 V rail voltage
  • Ensure WDI is driven to VDD or GND and serviced before the minimum watchdog timeout
  • Select suitable pullup resistors for RESET and WDO
