Controllers
MAX5902/MAX5903
General Description
The MAX5902/MAX5903 are hot-swap controllers that
allow a circuit card to be safely hot plugged into a live
backplane without causing a glitch on the power-sup-
ply rail. These devices operate from +9V to +72V and
provide the simplest hot-swap solution by eliminating all
external components except the external p-channel
MOSFET.
The MAX5902/MAX5903 limit the inrush current to the
load and provide a circuit-breaker function for overcurrent
protection. During startup the circuit-breaker function is
disabled and the MAX5902/MAX5903 limit the inrush cur-
rent by gradually turning on the external MOSFET. Once
the external MOSFET is fully enhanced, the circuit-break-
er function is enabled and the MAX5902/MAX5903 pro-
vide overcurrent protection by monitoring the voltage
drop across the external MOSFET’s on-resistance.
The MAX5902/MAX5903 include an undervoltage lock-
out (UVLO) function, ON/OFF control input, and a
power-good status output,
PGOOD
(MAX5902) or
PGOOD (MAX5903). A built-in thermal shutdown fea-
ture is also included to protect the external MOSFET in
case of overheating.
The MAX5902/MAX5903 offer latched or autoretry fault
management and are available with 300mV, 400mV or
500mV circuit-breaker thresholds. Both the MAX5902 and
MAX5903 are available in small SOT23 and TDFN pack-
ages, and are specified for the extended -40°C to +85°C
temperature range. For specific ordering information, see
the
Selector Guide
