DESCRIPTION
The TPS2398 and TPS2399 integrated circuits
are hot swap power managers optimized for use
in nominal 48-V systems. For redundant-supply
systems, they incorporate an improved circuit
breaker response that provides rapid protection
from short circuits, while still enabling plug-ins to
tolerate large transients that can be generated by
the sudden switchover to a higher voltage supply.
They are designed for supply voltage ranges up 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. Both devices provide load current slew
rate
and
peak
magnitude
limiting,
easily
programmed by sense resistor value and a single-
external capacitor.
