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.
