SGM25711B

2.5V to 18V High-Efficiency

Hot Swap Controller with Power-Limiting

GENERAL DESCRIPTION

FEATURES

The SGM25711B is a hot swap controller that allows a

board to be safely inserted or removed from a live

backplane. An internal circuit drives an external

N-MOSFET switch to control supply voltage from 2.5V

to 18V.

● Input Voltage Range from 2.5V to 18V

● Programmable MOSFET SOA Protection

● Accurate Current Limit at All Times

● Accurate 25mV Current Sense Threshold

● Power Good Output

● Fast Circuit-Breaker for Short-Circuit Protection

● Programmable Fault Timer

● Programmable Under-Voltage Threshold

● Active-Low for nPG and nFLT Pins

● Available in a Green MSOP-10 Package

The SGM25711B offers programmable current limit,

power-limiting and fault time to ensure that the external

MOSFET is always working within its safe operating

area. If the load current is higher than the set current for

more than the programmed time, the external MOSFET

will be shutdown. The SGM25711B restarts automatically

after a fault timeout delay. The low current sense

threshold of 25mV is very accurate, which allows the

use of smaller detection resistors resulting in lower

power losses and smaller size.

APPLICATIONS

Medical Systems

Storage Area Networks (SAN)

Plug-In Modules

This feature allows the user to easily design a high

reliability system. The device has power and fault

output functions to provide condition monitoring and

load protection.

Base Stations

SGM25711B is available in a Green MSOP-10 package.
