TPS1HA08DQPWPRQ1 is TI’s Version D automotive smart high-side switch for 12 V loads requiring low on-resistance, current monitoring, and active 80 A-class current limiting.

Best for

  • 12 V automotive resistive loads
  • heater and lighting loads
  • body-control outputs requiring current diagnostics

Avoid if

  • Immediate overcurrent switch-off is required
  • Continuous load current exceeds the thermal capability of the PCB and package
  • Inductive energy exceeds the specified clamp-energy capability without external suppression

Check before use

  • Validate current-limit behavior across temperature
  • Calculate junction temperature with the actual PCB thermal resistance
  • Verify SNS resistor scaling and ADC range
  • Check reverse-battery and inductive-load protection circuitry
