MP5990GMA-0000-P

MP5990GMA-0000-P is a fully integrated, PMBus compatible, compact hot-swap protection device. It contains a hot-swap controller and a high-side power MOSFET (HS-FET), which allow it to operate as a standalone device. The MP5990 can also operate as a hot-swap controller in parallel with the multi-phase MP5991. The device can achieve up to 50A of continuous output current (IOUT) per device at room temperature, and up to 60A of continuous IOUT with airflow. The device limits the backplane voltage drop by limiting the inrush current to the load while a circuit card is inserted into a live backplane power source. The MP5990 limits the internal MOSFET current (IFET) by controlling the gate voltage (VGATE) via the current limit (ILIMIT) reference input and soft-start ramp. Application includes hot swaps, PC cards, disk drives, servers, 5G telecom, networking, laptops.
