Description

The MPQ5068 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, and a low-power resistor from the ISET pin to ground controls the magnitude of the current limit. An internal charge pump drives the gate of the power device, allowing for a power FET with a very low on resistance of 7mΩ. The MPQ5068 includes an IMON option to produce a voltage proportional to the current through the power device, which is set by a resistor from the IMON pin to ground.

The MPQ5068’s fault protections include current-limit protection, thermal shutdown, and damaged-MOSFET detection. Both the current limit and thermal shutdown offer configurable auto-retry and latch-off mode. The device also features under-voltage protection.

The MPQ5068 is available in a QFN-22 (3mmx5mm) package and is AEC-Q100 qualified.
