+72V, SOT23/TDFN, Simple Swapper Hot-Swap

Controllers

General Description

Features

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.

♦ Wide +9V to +72V Operation

♦ Requires No External Sense Resistor

♦ Drives External p-Channel MOSFET

♦ Limits Inrush Current

♦ Circuit-Breaker Function

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.

♦ Less than 2mA Quiescent Current

♦ ON/OFF Input Permits Load Power-Supply

Control and Sequencing

♦ Adjustable Undervoltage Lockout

♦ Power-Good Output with +72V Rating

♦ Latching or Automatic Retry Fault Management

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.

♦ Thermal Shutdown Helps Protect the External

MOSFET

♦ Available in Two Small Packages

6-Pin TDFN and SOT23

Ordering Information

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 at the end of the data sheet.
