Product Description

The MP5073 provides up to 2A load protection over a 0.5V to 5.5V voltage range. With the small RDSON in tiny package, MP5073 is a very high efficiency and space saving solution for notebooks, tablets, and other portable/battery-operated applications.

With the soft start function, the MP5073 can avoid inrush current during circuit start up. MP5073 also provides programmable soft start time, output discharge functions, OCP and thermal shutdown features. 

The max load at the output (source) is current limited. This is accomplished by utilizing a sense FET topology. The magnitude of the current limit is controlled by an external resistor from the ILIM pin to ground. 

An internal charge pump drives the gate of the power device, allowing a very low on-resistance DMOS power FET of just 50mΩ.

The MP5073 is available in a tiny 12-pin 2mmx2mm QFN package.

Kit details

The EV5073-G-00A is an evaluation board for the MP5073, a low RDSON load switch with current limit.

The MP5073 is a load switch to provide 2.5A load protection covering 0.5V to 5.5V voltage range. With the small RDSON in tiny package, MP5073 provides very high efficient and space saving solution in notebook and tablet or other portable devices application.

The max load at the output (source) is current limited. This is accomplished by utilizing a sense FET topology. The magnitude of the current limit is controlled by an external resistor from the ILIM pin to ground.

The EV board can deliver a continuous 2A load current over 0.5V-to-5.5V operating input range.
