AEC-Q100 Grade 1timeout watchdog1.6 s watchdogopen-drain WDOSOT-23-8automotive

TPS3435CAKAGDDFRQ1 is an automotive timeout watchdog timer with a fixed 1.6 s watchdog interval, selectable 1x/2x/4x scaling, and an open-drain active-low WDO output.

Best for

  • Automotive MCU watchdog supervision
  • Low-power reset or NMI fault signaling
  • Applications needing a fixed watchdog interval with selectable scaling

Avoid if

  • A window watchdog is required
  • A push-pull watchdog output is required
  • The reset input cannot use an open-drain active-low signal

Check before use

  • Confirm the SET0 and SET1 logic state selects the intended timeout multiplier.
  • Provide a suitable pull-up resistor for the open-drain WDO output.
  • Confirm the 200 ms WDO assertion interval and no-startup-delay behavior meet firmware boot requirements.
