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.
