MP5990 - Fully Integrated Hot-Swap Solution

Description

The MP5990 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.

Features

  • to simplify system design, such as an integrated current mirror to monitor IOUT and integrated on-die temperature-sensing. This eliminates the need for an external current-sense power resistor, power MOSFET, and temperature-sense device. The MP5990 provides rich fault protections, such as input voltage (VIN) over-voltage protection (OVP), IOUT over-current protection (OCP), short-circuit protection (SCP), and overtemperature protection (OTP). The MP5990 detects power MOSFET gate, source, and dra.

DESCRIPTION The MP5990 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.
