Description
The MP5056 is a hot-swap protection device designed to protect circuitry on its output from transients on its input. It also protects its input from undesired shorts and transients coming from its output.
During start-up, the slew rate at the output limits the inrush current. An external capacitor connected to the SS pin controls the slew rate. The maximum output load is current-limited using a sense FET topology. A low-power resistor between the ISET pin and ground controls the magnitude of the current limit (ILIMIT). An internal charge pump drives the gate of the power device, which allows for a power MOSFET with a very low on resistance (RDS(ON)) of 7mΩ. The MP5056 includes an IMON option that produces a voltage proportional to the current flowing through the power device, which is set via a resistor connected between the IMON pin and ground.
Full protection features include current-limit protection, thermal shutdown, and damaged MOSFET detection. Both current-limit protection and thermal shutdown offer configurable auto-retry or latch-off mode. The device also features under-voltage lockout protection (UVLO).
The MP5056 is available in a QFN-22 (3mmx5mm) package.
