SGM25701A数据手册SGMICRO中文资料规格书

描述 Description

The SGM25701A 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 SGM25701A 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 output voltage increases to within the 1.4V range of the input voltage.

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 initial insertion delay time and fault detection time can also be adjusted by the user.

When a fault is detected, the device will go into auto-retry mode.

SGM25701A is available in a Green MSOP-10 package.
