The MP5920 is a hot-swap protection controller designed to protect circuitry on its output from transients on its input. The MP5920 allows a circuit board to be removed from or inserted into a live backplane and protects its input from undesired shorts and transients coming from its output.
The MP5920 works with an Intelli-Fuse, which can feed back the current, voltage, and temperature information to the MP5920. The Intelli-Fuse can be turned on or off through the ON pin. The MP5920 limits the Intelli-Fuse maximum load current by controlling the current limit reference voltage through CLPWM.
The MP5920 can be configured to a single output easily with several fuses in parallel.
The PMBus interface allows the MP5920 to read current, voltage, or temperature data and input power from a 12-bit ADC.
The MP5920 is available in a 32-pin TQFN (4mmx4mm) package.
