DESCRIPTION
The TPS2393A integrated circuit is a hot swap
power manager optimized for use in nominal
48-V systems. It operates with supply voltage
ranges from 20-V to 80-V, and is rated to
withstand spikes to 100 V. In conjunction with an
external N-channel FET and sense resistor, it can
be used to enable live insertion of plug-in cards
and modules in powered systems. It 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 and removal detection. The associated
debounce delay applies to both actions. A power
good
(PG)
output
enables
downstream
converters. The TPS2393A also provides the
basic hot swap functions of electrical isolation of
faulty cards, filtered protection against nuisance
overcurrent trips, and single-line fault reporting.
The TPS2393A periodically retries the load in the
event of a fault.
