MONOLITHIC POWER SYSTEMS (MPS) MPQ5072GG-AEC1-P

MPQ5072 is a programmable load switch that provides 1A of load protection across a 0.5V to 5.5V voltage range. With low RDS(ON) in a tiny package, the MPQ5072 provides a highly efficient, space-saving solution for notebooks, tablets and other portable device applications. MPQ5072’s soft start (SS) function avoids inrush current during circuit start-up. It 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 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 power device gate, allowing a low on resistance DMOS power FET of 50mohm. It available in a tiny, space saving QFN-12 (2mmx2mm) package. Applications include notebook and tablet computers, portable devices, solid state drives (SSDs) and handheld devices.
