The SGM25701 is a positive hot swap controller that allows a board to be safely inserted or removed from a live backplane. Inrush current control function can effectively reduce the voltage drop on the power supply rail.

The SGM25701 offers programmable power-limiting and current limit to ensure that the external MOSFET operates within its safe operating area (SOA) at all times.

The chip has a good output indication function when the VOUT increases to within the 1.4V range of the VIN.

Programmable under-voltage lockout or over-voltage lockout is used to turn off the device if the VIN drops below or raises over a threshold value. The fault detection time and initial insertion delay time can also be adjusted by the user.

The SGM25701B will latch off when a fault is detected, while the SGM25701A will go into auto-retry mode.

SGM25701 is available in a Green MSOP-10 package.
