DESCRIPTION

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.
