About This Product

■Summary

The MP5021B is a hot-swap protection device designed to protect output circuitry from input transients. It also protects the input from unwanted shorts and transients coming from the output. During start-up, the output slew rate limits the inrush current. An external capacitor on SS controls the slew rate. The maximum output load is current limited using a sense FET topology, and a low power resistor from ISET to ground controls the amount of current limit. An internal charge pump drives the gate of the power device, enabling the power FET to have an extremely low on-resistance of 7mΩ. The MP5021B includes an IMON option that generates a voltage proportional to the current flowing through the power device, set by a resistor from IMON to ground. The MP5021B includes an optional discharge feature that provides a discharge path to the external output capacitor when the device is disabled. Fault protection includes current limit protection, thermal shutdown, and damaged MOSFET detection. Both current limit and thermal shutdown feature user-configurable auto-retry and latch-off modes. The device also features overvoltage protection (OVP) and undervoltage protection (UVP). The MP5021B is available in a 3mm x 5mm QFN package.
