Datasheet

概要

The MP5921 is a monolithic, integrated controller and switch that contains a high-side MOSFET and other circuitries that enable it to work in standalone operation or to be controlled by a hot-swap controller. The MP5921 drives up to 50A of continuous current per device at room temperature. With air flow, the continuous current can reach 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. The MP5921 limits the internal MOSFET current by controlling the gate voltage through the current limit reference input and soft-start ramp.

The MP5921 offers many features to simplify system design. It provides an integrated current mirror to monitor the output current and on-die temperature sensing, 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 can feedback to the hot-swap controller via the fault reporting output (GOK). The MP5921 can be paralleled for higher current applications. All devices in parallel share current actively during soft start.

The MP5921 is available in a QFN-28 (4mmx5mm) package.
