Description
The MP5991 is an integrated, monolithic controller and switch with a power MOSFET and other circuitry that allows it to operate alone or to be controlled via a hot-swap controller. The device can drive up to 50A of continuous output current (IOUT) per device at room temperature, and up to 60A of continuous IOUT with air flow.
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. It limits the internal MOSFET current (IFET) by controlling the gate voltage (VGATE) via the current limit (ILIMIT) reference input and soft-start (SS) ramp.
The MP5991 provides many features to simplify system design, such as an integrated current mirror to monitor IOUT and the integrated on-die temperature sense. This eliminates the need for an external current-sense power resistor, power MOSFET, and temperature-sense device.
The IC detects the power MOSFET's gate, source, and drain short conditions. It also provides feedback to the hot-swap controller via the fault-reporting output (GOK). The MP5991 can operate in parallel for high-current applications. During start-up, all of the devices in parallel actively share current.
The MP5991 is available in an LGA-32 (5mmx5mm) package.
