eFuseauto-retry55 A70 A peak4.5 V to 16 Vcurrent monitorhot-swapWQFN

TPS259841RZJR is a high-current, auto-retry eFuse for 4.5 V to 16 V power rails, integrating a low-resistance FET, programmable protection, inrush control, and analog monitoring.

Best for

  • High-current 12 V power-path protection
  • Hot-swap and hot-plug power rails
  • Parallel eFuse power paths requiring current sharing

Avoid if

  • The input rail can routinely exceed the 16 V recommended operating limit
  • A single-device solution must continuously carry more than 55 A RMS
  • A design cannot provide controlled startup and adequate thermal layout

Check before use

  • Verify startup dissipation against the 10 W√s FET SOA limit
  • Select transient suppression for input positive and output negative inductive spikes
  • Confirm SWEN pullup availability independent of the switched output
