MAX5932ESA-MAX5932ESA+
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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
