Description
The TPS2490 and TPS2491 +48 V hot swap power manager (HSPM)
provides highly integrated supply control of 9V to 80V positive supplies with
a minimum number of external components. These hot-swap controllers
operate an external N-channel MOSFET device to safely switch power to
downstream loads. A power MOSFET can be destroyed if operated outside
its safe operating area (SOA) curve, which typically includes limitations on
current, voltage and power. In order to assure that the SOA is not exceeded,
the hot-swap controller contains independently adjustable current- and
power-limit circuitry. If a fault persists beyond a user-defined period of time, the
HSPM turns off the power MOSFET. Depending upon which design option is
chosen, the part either remains latched off (TPS2490) until the enable is
cycled, or it automatically restarts (TPS2491) after a time delay.
These devices can be used on plug-in cards and on back-planes to limit inrush
current, control load turn-on, enable down-stream dc-to-dc converters, isolate
faulted loads, and eliminate nuisance shutdowns.
