Power Management (PMIC)

AEC-Q100Automotive watchdogTimeout watchdogOpen-drain WDOExternal timing capacitorSOT-23-8

TPS3435AFACADDFRQ1 is an automotive timeout watchdog with externally programmed watchdog and reset-output timing, 10 s startup delay, and open-drain active-low WDO.

Best for

  • Automotive microcontroller supervision
  • Low-power watchdog monitoring
  • Applications requiring externally adjustable timeout and reset pulse timing

Avoid if

  • A fixed watchdog timeout is required without external timing capacitors
  • A push-pull reset output is required
  • The system cannot tolerate the selected 10 s startup delay

Check before use

  • Select CWD within 1.5 nF to 1000 nF.
  • Select CRST within 1.5 nF to 1800 nF.
  • Provide an appropriate pull-up resistor for the open-drain WDO output.
