MP5921 Datasheet Hot-swap Intelli-fuse Solution

Manufacturer: Monolithic Power Systems

Overview: MP5921 16V, 50A, 1mΩ RDS(ON), Hot-Swap Intelli-Fuse Solution.

General Description

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.

Key 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.
