Micrel – MIC95410: Load Switch Delivers 7A Continuous Current in 1.2 x 2.0mm Package

Micrel_March2015_pg22micrel-logo
The MIC95410 is a high side load switch for computing and ultra dense embedded computing boards where high-current low voltage rails from sub-1V to 5.5V have to be sectioned. The integrated 6.6mΩ RDS(ON) N-channel MOSFET ensures low voltage drop and low power dissipation while delivering up to 7A of load current. The MIC95410 is internally powered by a separated bias voltage from 2.7V to 9V. It includes a TTL-logic level to gate a voltage translator driving a charge pump, and an output discharge function when disabled. The OFF-state current from bias supply (VS) and the power switch OFF-state leakage current (IOFF) are both below 1uA.
