The EV5920-5048-V-00A is an evaluation board designed to demonstrate the capabilities of the MP5920 and MP5048. The MP5920 is a hot-swap protection controller that protects the circuitry from transients on the input. It works with an Intelli-Fuse that feeds back current, voltage, and temperature information to the IC. The Intelli-Fuse can be turned on and off via the ON pin. The MP5048 is a monolithic, integrated controller and switch that can operate as a standalone device, or be controlled via a hot-swap controller.
The MP5920 limits the Intelli-Fuse’s maximum load current by controlling the current limit reference voltage via the CLPWM pin. The PMBus interface allows the IC to read the current, voltage, and temperature data, as well as input power from a 12-bit analog-to-digital converter (ADC).
The MP5048 can drive up to 15A of continuous current per device. It simplifies system design by providing an integrated solution to monitor the output current (IOUT) and die temperature. This eliminates the need for an external current-sense power resistor, power MOSFET, or thermal sense. The MP5048 detects the power MOSFET gate, source, and drain short conditions to provide feedback to the controller. It can also be paralleled for higher current applications.
The MP5920 is available in a TQFN-32 (4mmx4mm) package, and the MP5048 is available in a QFN-30 (5mmx5mm) package.
