Load Drivers

high-side switchload switchcurrent limitedactive-low enablefault flagreverse-current blockingSOT-23-5L

WS4612EBB-5/TR is an active-low, current-limited high-side load switch for 2.5 V to 5.5 V rails. It combines reverse-current blocking, output auto-discharge, thermal shutdown, and an open-drain fault indication.

Best for

  • USB peripheral power switching
  • 3.3 V and 5 V load distribution
  • Low-side-control systems requiring an active-low load switch

Avoid if

  • A current limit higher than 1.6 A maximum threshold is required
  • An active-high enable input is required without logic inversion
  • A documented lifecycle status is mandatory

Check before use

  • Enable polarity and logic thresholds
  • Current-limit tolerance versus load startup current
  • Thermal behavior during overload or short circuit
  • Fault-flag pull-up implementation
