DESCRIPTIONThe TPS2392 and TPS2393 integrated circuits are hot
swap power managers optimized for use in nominal
−48-V systems. They operate with supply voltage
ranges from −20-V to −80-V, and are rated to withstand
spikes to −100 V. In conjunction with an external
N-channel FET and sense resistor, they can be used to
enable live insertion of plug-in cards and modules in
powered systems. Each device provides load current
slew rate control and peak magnitude limiting.
Undervoltage and overvoltage shutdown thresholds
are easily programmed via a three-resistor divider
network. In addition, two active-low, debounced inputs
provide plug-in insertion detection. A power good (PG)
output enables downstream converters. The TPS2392
and TPS2393 also provide the basic hot swap functions
of electrical isolation of faulty cards, filtered protection
against nuisance overcurrent trips, and single-line fault
reporting. The 44-pin part supports designs where
telecomm creepage and clearance requirements must
be followed.
The TPS2392 latches off in response to current faults,
while the TPS2393 periodically retries the load in the
event of a fault.
