TI TPS24710DGSR

TPS24710/11/12/13 is a simple-to-use 2.5V to 18V hot-swap controller that safely drives an external N-channel MOSFET. Programmable current limiting and fault timer protection prevent excessive inrush current during power supply and load startup. After startup, current exceeding the user-selected threshold is allowed to flow until the end of a programmed timeout period, except in extreme overload conditions where the load is abruptly disconnected from the supply. The 25mV low current-sense threshold delivers high accuracy, allowing the use of small, efficient sense resistors to reduce power dissipation and board footprint.

A programmable power-limiting feature ensures the external MOSFET always operates within its safe operating area (SOA). This enables the use of smaller MOSFETs while improving system reliability. Power-good and fault outputs are provided for status monitoring and downstream load control.
