open-in-new Find other eFuses & hot swap controllers

Description

The TPS24700/1 is an easy-to-use, 2.5 V to 18 V, hot-swap controller that drives an external N-channel MOSFET. The programmable current limit and fault time protect the supply and load from excessive current at startup. After startup, currents above the user-selected limit are allowed to flow until programmed timeout – except in extreme overload events when load is immediately disconnected from source. The low, 25-mV current sense threshold is highly accurate and allows use of smaller, more-efficient sense resistors, yielding lower power loss and smaller footprint. A power-good output is provided for status monitoring and downstream load control.

TPS24700/1 replaces the LTC4211 in existing designs with no PCB board changes and only minor external component changes – yielding a more accurate, efficient solution.
