MP5921 is a monolithic integrated controller and switch. It contains a high-side MOSFET and other circuitry that enables it to work as stand-alone or to be controlled by a hot-swap controller. MP5921 drives up to 50 A of continuous current per device at room temperature, while with air flow, the continuous current can reach to 60A.
The MP5921 limits the inrush current to the load when a circuit card is inserted into a live backplane power source, thereby limiting the backplane’s voltage drop. MP5921 limits the internal MOSFET current by controlling the gate voltage through the current limit reference input.
MP5921 offers many features to simplify the system design. It provides an integrated solution to monitor the output current and the die temperature, eliminating the need for an external current-sense power resistor, power MOSFET, and thermal sense device.
The MP5921 detects the power FET gate, source, and drain short conditions and feedback to controller. Also, MP5921 can be paralleled for higher current applications.
The MP5921 is available in 4mmx5mm QFN package.
