Product Description

The MP5021B 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.

An internal charge pump drives the gate of the power device, allowing for a power FET with a very low ON resistance of 7m?.

The MP5021B includes an optional discharge function that provides a discharge path for the external output capacitor when the part is disabled. Fault protection includes current limit, thermal shutdown and damaged MOSFET detection. Both of the current limit and thermal shutdown have user settable auto retry and latch off mode. The device also features over-voltage protection and under-voltage protection

The MP5021B is available in 3mmx5mm QFN package.

16V, 7mΩ RDS_on Hot-Swap Protection Device with Current Monitoring

The MP5021B is a hot-swap protection device designed to protect circuitry on its output from transients on its input. Also, it protects its input from undesired shorts and transients coming from its output.
At start-up, the slew rate at the output limits the inrush current. An external capacitor at SS controls the slew rate.
The maximum output load is current limited using a sense FET topology where a low-power resistor from ISET to ground controls the magnitude of the current limit.
An internal charge pump drives the gate of the power device, allowing a power FET with a very low on resistance of 7 mΩ.
The MP5021B includes an IMON option to produce a voltage proportional to the current through the power device, as set by a resistor from IMON to ground.
The MP5021B 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 protection, thermal shutdown, and damaged MOSFET detection. Both the current limit and thermal shutdown have user-settable auto-retry and latch-off mode. Also, the device features over-voltage protection (OVP) and under-voltage protection (UVP).
The MP5021B is available in a 3mm x 5mm QFN package.
