The TPS2394 is a hot swap power manager which can provide inrush limit, over current protection, short circuit protection. The TPS2394 operates with supply voltages from −12 V to −80 V, and withstands input transient to −100 V.

The TPS2394 uses a power FET to provide load current slew rate control and peak current limiting that is programmed by one resistor and one capacitor. The device also provides a power good output to enable down-stream power converters and a fault output to indicate load problems.
