FEATURES
DESCRIPTION
Replaces OR-ing Diodes
The TPS2350 is a hot swap power manager
Operating Supply Range of
–12 V to –80 V
optimized for replacing OR-ing diodes in redundant
Withstands Transients to
–100 V
power
–48-V systems. The TPS2350 operates with
supply voltages from
–12 V to –80 V, and withstands
Programmable Current Limit
spikes to
–100 V.
Programmable Linear Inrush Slew Rate
The TPS2350 uses two power FETs as low voltage
Programmable UV/OV Thresholds

diodes
to
efficiently
select
between
two

redundant power supplies. This minimizes system

power dissipation and also minimizes voltage drop
through the power management chain.
Power Good and Fault Outputs
14-Pin SOIC and TSSOP Package
The TPS2350 also uses a third power FET to provide
load current slew rate control and peak current
limiting that is programmed by one resistor and one
