Product Description

The MP5023 is a hot-swap protection device designed to protect circuitry on its output from transients on its input. The MP5023 also protects its input from undesired shorts and transients coming from its output.

During start-up, inrush current is limited by the slew rate at the output. The slew rate is controlled by the external capacitor at SS.

The maximum load at the output is currentlimited through on-die current sense technology. The magnitude of the current limit is controlled by a low-power resistor from ISET to ground.

An internal charge pump drives the gate of the power device, allowing for a power MOSFET with a very low on resistance of 1.1mΩ.

The MP5023 includes an IMON option that produces a voltage proportional to the current through the power device set by a resistor from IMON to ground.

The PMBusTM interface allows the MP5023 to read current, voltage, temperature data, and input power from the internal ADC.

The MP5023 includes an optional discharge function through the PMBusTM that provides a discharge path for the external output capacitor when the part is disabled.

Fault protection includes current limiting, thermal shutdown, and damaged MOSFET detection. Both current limit and thermal shutdown have auto-retry and latch-off modes via the PMBusTM interface that can be set by the user.

The MP5023 also features overvoltage protection (OVP) and under-voltage protection (UVP). The MP5023 is available in a small FCQFN-24 package (4mmx5mm).
