MAX5932

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.

The MAX5932 provides a power-good output (PWRGD) to indicate the status of the output voltage. For a variety of PWRGD/PWRGD-bar, 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.
