产品描述

The MP5022A 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. At start-up, inrush current is limited by the slew rate at the output. The slew rate is controlled by external capacitor at the SS pin. The maximum load at the output is current limited through a sense FET topology. The magnitude of the current limit is controlled by a low-power resistor from the ISET pin to ground. An internal charge pump drives the gate of the power device, allowing for a power FET with a very low on resistance of 3mΩ. The MP5022A includes an IMON option that produces a voltage proportional to current through the power device set by a resistor from this pin to ground. The MP5022A includes an optional discharge function that provides a discharge path for the external output capacitor when the part is disabled. Fault protections include current limit, thermal shutdown, and damaged MOSFET detection. The device also features over-voltage protection and under-voltage protection. The MP5022A is available in a QFN-22 (3mmx5mm) package.
