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.
