Power Management (PMIC)

eFusepower multiplexeractive ORingreverse-current blockinghot swapcircuit breakerWQFN-20

TPS25944LRVCR is a latched 5 A-class eFuse power multiplexer for protected active-ORing, hot-swap, and redundant power-path designs.

Best for

  • 2.7 V to 18 V protected power rails
  • active ORing and redundant supplies
  • hot-swap loads requiring reverse blocking

Avoid if

  • A continuously regulated current-limiter response is required instead of timed circuit breaking
  • The application requires operation beyond the exact orderable-device temperature rating without confirmation

Check before use

  • Use RILIM within the specified 16.9 kΩ to 150 kΩ recommended range.
  • Connect all IN pins together and all OUT pins together.
  • Solder the exposed thermal pad to ground with thermal vias.
  • Validate transient suppression for inductive source or load paths.
