Texas Instruments' 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.
