-48V Hot-Swap Controller

with External R

SENSE

General Description

Features

The MAX5920A/MAX5920B are hot-swap controllers that

allow a circuit card to be safely hot plugged into a live

backplane. The MAX5920A/MAX5920B operate from

-20V to -80V and are well-suited for -48V power systems.

These devices are pin and function compatible with the

LT4250 and pin compatible with the LT1640.

ꢀ Allows Safe Board Insertion and Removal

from a Live -48V Backplane

ꢀ Pin- and Function-Compatible with LT4250L

(MAX5920A)

ꢀ Pin-Compatible with LT1640L (MAX5920A)

The MAX5920A/MAX5920B provide a controlled turn-on

to circuit cards preventing glitches on the power-supply

rail and damage to board connectors and components.

The MAX5920A/MAX5920B provide undervoltage, over-

voltage, and overcurrent protection. These devices

ensure the input voltage is stable and within tolerance

before applying power to the load.

ꢀ Pin- and Function-Compatible with LT4250H

(MAX5920B)

ꢀ Pin-Compatible with LT1640H (MAX5920B)

ꢀ Circuit-Breaker Immunity to Input Voltage Steps

and Current Spikes

ꢀ Withstands -100V Input Transients with No

Both the MAX5920A and MAX5920B protect a system

against overcurrent and short-circuit conditions by turn-

ing off the external MOSFET in the event of a fault con-

dition. The MAX5920A/MAX5920B also provide

protection against input voltage steps. During an input

voltage step, the MAX5920A/MAX5920B limit the cur-

rent drawn by the load to a safe level without turning off

power to the load.

External Components

ꢀ Programmable Inrush and Short-Circuit Current

Limits

ꢀ Operates from -20V to -80V

ꢀ Programmable Overvoltage Protection

ꢀ Programmable Undervoltage Lockout

ꢀ Powers Up into a Shorted Load

Both devices feature an open-drain power-good status

output (PWRGD for the MAX5920A or PWRGD for the

MAX5920B) that can be used to enable downstream

converters. A built-in thermal-shutdown feature is also

included to protect the external MOSFET in case of

overheating.

ꢀ Power-Good Control Output

ꢀ Thermal Shutdown Protects External MOSFET

The MAX5920A/MAX5920B are available in an 8-pin SO

package. Both devices are specified for the extended

-40°C to +85°C temperature range.
