The MAX5924/MAX5925/MAX5926 1V to 13.2V hot-swap

controllers allow the safe insertion and removal of circuit

cards into live backplanes. These devices hot swap sup-

plies ranging from 1V to 13.2V provided that the device

supply voltage, V

swapped supply, V

The MAX5924/MAX5925/MAX5926 hot-swap controllers

limit the inrush current to the load and provide a circuit-

breaker function for overcurrent protection. The devices

operate with or without a sense resistor. When operat-

ing without a sense resistor, load-probing circuitry

ensures a short circuit is not present during startup,

then gradually turns on the external MOSFET. After the

load probing is complete, on-chip comparators provide

overcurrent protection by monitoring the voltage drop

across the external MOSFET on-resistance. In the event

of a fault condition, the load is disconnected.

The MAX5924/MAX5925/MAX5926 include many inte-

grated features that reduce component count and

design time, including programmable turn-on voltage,

slew rate, and circuit-breaker threshold. An on-board

charge pump provides the gate drive for a low-cost,

external n-channel MOSFET.

The MAX5924/MAX5925/MAX5926 are available with

open-drain PGOOD and/or PGOOD outputs. The

devices also feature a circuit breaker with temperature-

compensated R

a selectable 0ppm/°C or 3300ppm/°C temperature coef-

ficient. The MAX5924 temperature coefficient is

0ppm/°C and the MAX5925 temperature coefficient is

3300ppm/°C. Autoretry and latched fault-management

configurations are available (see the Selector Guide).
