The MPQ5073 is a load switch to provide 2A load protection covering 0.5V to 5.5V voltage range. With the small RDSON in tiny packages, MPQ5073 provides very high efficient and space saving solution in notebook and tablet or other portable devices application.
With the soft start function, the MPQ5073 can avoid inrush current during circuit start up. MPQ5073 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 50mO.
Tiny QFN-12 (2mmx2mm) of MPQ5073 is available in space saving package.
