MPQ5073 5.5V, 2A Low R Load Switch DSON with Programmable Current Limit AEC-Q100 Qualified DESCRIPTION FEATURES The MPQ5073 is a load switch to provide 2A Guaranteed Industrial/Automotive Temp load protection covering 0.5V to 5.5V voltage Range Limits range. With the small R in tiny packages, DSON Large V Range from 0.5V to 5.5V IN MPQ5073 provides very high efficient and <5A Shutdown Current space saving solution in notebook and tablet or Integrated 50m Low R FETs DSON other portable devices application. Typical 2A Load Current Range Push Pull PG Indicator With the soft start function, the MPQ5073 can Adjustable Start Up Slew Rate avoid inrush current during circuit start up. MPQ5073 also provides programmable soft Output discharge function start time, output discharge functions, OCP and <200ns Short-Circuitry Response Protection thermal shutdown features. Thermal Protection Small QFN-12 (2mmx2mm) Package for The max load at the output (source) is current Space Saving limited. This is accomplished by utilizing a Available in AEC-Q100 Qualified Grade sense FET topology. The magnitude of the current limit is controlled APPLICATIONS by an external resistor from the ILIM pin to ground. Notebook and Tablet Computers Portable Devices An internal charge pump drives the gate of the Solid State Drivers power device, allowing a very low on-resistance Handheld Devices DMOS power FET of just 50m. All MPS parts are lead-free, halogen free, and adhere to the RoHS directive. For Tiny QFN-12 (2mmx2mm) of MPQ5073 is MPS green status, please visit MPS website under Quality Assurance. MPS and The Future of Analog IC Technology are Registered Trademarks of available in space saving package. Monolithic Power Systems, Inc.
