SGM25701 Positive High-Voltage Hot Swap and Inrush Current Controller with Power-Limiting
■ 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.
