General Description
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
CC
, is at or above 2.25V and the hot-
swapped supply, V
S
, does not exceed V
CC
.
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 configurable 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
MAX5925/MAX5926 also feature a circuit breaker with
temperature-compensated R
DS(ON)
sensing. The
MAX5926 features a selectable 0ppm/癈 or 3300ppm/癈
temperature coefficient. The MAX5924 temperature coef-
ficient is 0ppm/癈 and the MAX5925 temperature coeffi-
cient is 3300ppm/癈. Autoretry and latched fault-
management configurations are available (see the
Selector Guide).
