Supervisors

AEC-Q1003.0 V supervisorextended watchdogopen-drain resetVSON-8

TPS3851G30EQDRBRQ1 is an AEC-Q100 Grade 1 supervisor for a nominal 3.0 V rail, combining undervoltage reset supervision with an extended programmable watchdog.

Best for

  • Automotive 3.0 V rail supervision
  • Microcontroller watchdog monitoring
  • ADAS and ECU control electronics

Avoid if

  • A different monitored-rail threshold is required
  • A push-pull reset output is required
  • The extended watchdog timing range is unsuitable

Check before use

  • Verify the selected G30 -4% threshold against the system brownout requirement.
  • Use a COG ceramic CWD capacitor when watchdog timing accuracy is important.
  • Connect the exposed thermal pad to the ground plane.
