FEATURES
DESCRIPTION
Operating Supply Range of –12 V to –80 V
Withstands Transients to –100 V
The TPS2394 is a hot swap power manager which
can provide inrush limit, over current protection, short
Programmable Current Limit
circuit protection. The TPS2394 operates with supply
Programmable Linear Inrush Slew Rate
voltages from
12 V to 80 V, and withstands input
Programmable UV/OV Thresholds
transient to
100 V.
Programmable UV and OV Hysteresis
The TPS2394 uses a power FET to provide load
Fault Timer to Eliminate Nuisance Trips
current slew rate control and peak current limiting that
is programmed by one resistor and one capacitor.
Power Good and Fault Outputs
The device also provides a power good output to
14-Pin TSSOP Package
enable down-stream power converters and a fault
output to indicate load problems.
APPLICATIONS
–48-V Distributed Power Systems
Central Office Switching
ATCA Systems
Base Stations
