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