TPMAX40203AUK+T is a 5-pin, active-high high-side load switch for 1.5 V to 5.5 V systems, with 2 A maximum continuous switch current and low standby consumption.

Best for

  • High-side switching of low-voltage electronic loads
  • USB and portable-device power control
  • Battery-powered designs requiring low off-state current

Avoid if

  • The application requires a specified overcurrent or short-circuit protection function not documented in this datasheet
  • The load current or thermal conditions exceed the device ratings

Check before use

  • Confirm the 2 A operating point is thermally achievable on the target PCB
  • Verify enable logic levels over the complete input-voltage range
  • Resolve the datasheet's inconsistent headline current specifications
