MAX5932 - Hot-Swap Controller

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 backplane power-supply rail.

Features

  • a programmable 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 M.

MAX5932 19-3264; Rev 0; 4/04 EVAALVUAAILTAIOBNLEKIT 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 backplane power-supply rail. This device is pin and function compatible to LT1641-1. The MAX5932 features a programmable 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.
