MAX5924BEUB-MAX5925DEUB
1 V to 13.2 V, n-channel hot-swap controller require no sense resistor
General DescriptionThe 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, VCC, is at or above 2.25V and the hot-
swapped supply, VS, does not exceed VCC.
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 PGOODoutputs. The
devices also feature a circuit breaker with temperature-
compensated RDS(ON)sensing. The MAX5926 features
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).

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.
