2.5V to 18V High-Efficiency Hot Swap Controller with Power-Limiting
GENERAL DESCRIPTION

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.

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.

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.

SGM25711B is available in a Green MSOP-10 package.
