About This Product

■Summary

The MP5991 is an integrated monolithic controller and switch with power MOSFETs and other circuitry that can operate alone or be controlled via a hot-swap controller. The device can drive up to 50A continuous output current (IOUT) per device at room temperature and up to 60A IOUT with airflow. The device limits backplane voltage drops by limiting inrush current to the load while a circuit card is inserted into a live backplane power supply. Current Limit (ILIMIT) Limits the internal MOSFET current (IFET) by controlling the gate voltage (VGATE) via the reference input and soft-start lamp. The MP5991 offers many features that simplify system design, including an integrated current mirror to monitor IOUT and integrated on-die temperature sensing. This eliminates the need for external current-sensing power resistors, power MOSFETs, and temperature-sensing devices. The IC detects short-circuit conditions between the gate, source, and drain of the power MOSFET. It also provides feedback to the hot-swap controller through the fault reporting output (GOK). The MP5991 is capable of parallel operation for high current applications. During startup, all devices in parallel actively share current. The MP5991 is available in a low profile LGA-32 (5mm x 5mm) package.
