DESCRIPTION
MP5921 is a monolithic integrated controller
and switch. It contains a high-side MOSFET
and other circuitry that enables it to work as
stand-alone or to be controlled by a hot-swap
controller. MP5921 drives up to 50 A of
continuous current per device at room
temperature, while with air flow, the continuous
current can reach to 60A.
The MP5921 limits the inrush current to the
load when a circuit card is inserted into a live
backplane power source, thereby limiting the
backplane’s voltage drop. MP5921 limits the
internal MOSFET current by controlling the gate
voltage through the current limit reference input.
MP5921 offers many features to simplify the
system design. It provides an integrated
solution to monitor the output current and the
die temperature, 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
feedback to controller. Also, MP5921 can be
paralleled for higher current applications.
The MP5921 is available in 4mmx5mm QFN
package.

QUICK START GUIDE
1. Attach the positive and negative terminals of the load to the VOUT and GND terminals on demo
board, respectively.
2. Preset the power supply output to be 12V, and then turn off the power supply.
3. Attach the positive and negative terminals of the power supply to the VIN and GND terminals on
demo board, respectively.
4. Turn on the VIN power supply.
USER GUIDE
The EV5921-V-01A can be configured as 1~4 phase operation application by adjusting some
