Positive High-Voltage, Hot-Swap Controller
General Description
The MAX5932 is a fully integrated hot-swap controller for
+9V to +80V positive supply rails. The MAX5932 allows
for the safe insertion and removal of circuit cards into a
live backplane without causing glitches on the back-
plane power-supply rail. This device is pin and function
compatible to LT1641-1. The MAX5932 features a pro-
grammable foldback-current limit. If the device remains
in current limit for more than a programmable time, the
external n-channel MOSFET latches off. Other features
include a programmable undervoltage lockout and a
programmable output-voltage slew rate through an
external n-channel MOSFET.
The MAX5932 provides a power-good output (PWRGD)
to indicate the status of the output voltage. For a variety
of PWRGD/PWRGD, latch/autoretry-fault management,
autoretry duty-cycle options, refer to the MAX5933 and
MAX5934 data sheets.
The MAX5932 operates in the -40°C to +85°C extended
temperature range. This device is available in an
8-pin SO package.
