Power Management (PMIC)

eFusepower MUXcircuit breakeractive ORingreverse-current blockingWQFN-20

TPS25944ARVCR is an auto-retry, circuit-breaker eFuse power MUX for 2.7 V to 18 V rails, combining hot-swap control, reverse-current blocking, programmable protection, and current monitoring.

Best for

  • Protected 2.7 V to 18 V power paths
  • Active ORing and redundant supplies
  • Hot-swap rails requiring reverse-current blocking

Avoid if

  • A fixed current limit without external programming is required
  • The application cannot tolerate the circuit-breaker timeout behavior
  • PCB thermal area for the exposed pad is limited

Check before use

  • Validate inrush current against output capacitance and dVdT programming
  • Confirm ILIM resistor selection and fault response
  • Use short, wide power traces and a grounded thermal pad with vias
