TPS12111LQDGXRQ1 is an automotive smart high-side driver for external back-to-back N-channel MOSFETs, with a dedicated precharge output for large capacitive loads.

Best for

  • Automotive protected high-side power paths
  • Back-to-back N-channel MOSFET control
  • Precharging large output capacitance before main-path turn-on

Avoid if

  • An integrated protected load switch is required
  • No external MOSFET or current-sense network can be accommodated

Check before use

  • Verify the 3.5 V to 40 V operating range and 45 V absolute maximum against system transients
  • Confirm MOSFET VGS rating for the approximately 12 V charge-pump drive
  • Validate precharge timing and inrush current with the actual output capacitance
