产品概述
The TPS2390 and TPS2391 integrated circuits
are hot swap power managers optimized for use
in nominal –48-V systems. 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.
They also provide single-line fault reporting,
electrical isolation of faulty cards, and protection
against nuisance overcurrent trips. The TPS2390
latches off in response to current faults, while the
TPS2391 periodically retries the load in the event
of a fault.
