Supervisors

voltage supervisorwatchdog timerautomotive1.8 VVSON

TPS3851H18EQDRBRQ1 is an automotive 1.8 V voltage supervisor with a 7% undervoltage threshold and integrated extended-timing watchdog.

Best for

  • Automotive microcontroller supervision
  • ADAS and ECU power-rail monitoring
  • Systems requiring an independent watchdog fault output

Avoid if

  • A push-pull reset output is required
  • The monitored rail or timing requirements do not match the fixed 1.8 V and -7% option

Check before use

  • Confirm VDD remains within 1.6 V to 6.5 V
  • Confirm RESET and WDO pull-up voltage compatibility
  • Select the correct CWD configuration and capacitor tolerance
