-100V, SOT23/TDFN, Simple Swapper

Hot-Swap Controllers

General Description

Features

♦ Wide -9V to -100V Operation

♦ Requires No External Sense Resistor

♦ Drives External N-Channel MOSFET

♦ Limits Inrush Current

The MAX5900/MAX5901 are SOT23/TDFN hot-swap con-

trollers that allow a circuit card to be safely hot-plugged

into a live backplane without causing a glitch on

the power-supply rail. These devices operate from -9V to

-100V and provide the simplest hot-swap solution by

eliminating all external components except an external

n-channel MOSFET.

♦ Circuit-Breaker Function

♦ Less than 1mA Quiescent Current

The MAX5900/MAX5901 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 MAX5900/MAX5901 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 MAX5900/MAX5901 pro-

vide overcurrent protection by monitoring the voltage

drop across the external MOSFET’s on-resistance.

♦ ON/OFF Input Permits Load Power-Supply

Control and Sequencing

♦ Adjustable Undervoltage Lockout

♦ Power-Good Output with 100V Rating

♦ Latching or Automatic Retry Fault Management

♦ Thermal Shutdown Helps Protect the External

MOSFET

♦ Space-Saving 6-Pin SOT23 and TDFN Packages

The MAX5900/MAX5901 include an undervoltage lock-

out (UVLO) function, ON/OFF control input, and a power-

good status output, PGOOD (MAX5900) or PGOOD

(MAX5901). A built-in thermal shutdown feature is also

included to protect the external MOSFET in case of over-

heating.

The MAX5900/MAX5901 offer latched or autoretry fault

management and are available with 200mV, 300mV, or

400mV circuit-breaker thresholds. Both the MAX5900 and

MAX5901 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
