Description
The MPQ5071 is a programmable load switch that provides 0.5A of load protection across a 0.5V to 5.5V voltage range. With low RDS(ON) in a tiny package, the MPQ5071 provides a highly efficient, space-saving solution for notebooks, tablets, and other portable device applications. The MPQ5071’s soft start (SS) function avoids inrush current during circuit start-up.
The MPQ5071 also provides a programmable soft start time, output discharge functions, overcurrent protection (OCP), and thermal shutdown. The maximum load at the output source is current-limited, which is accomplished utilizing a sense MOSET topology.
The magnitude of the current limit is controlled by an external resistor from the ILIM pin to ground (GND). An internal charge pump drives the power device gate, allowing a low on resistance DMOS power MOSET of just 50mΩ.
The MPQ5071 is available in a tiny, space-saving QFN-12 (2mmx2mm) package.
