MIC95410 6.6m R , 7A, 5.5V V Load Switch in DS(ON) IN 1.2mm 2.0mm QFN Package General Description Features The MIC95410 is a high-side load switch for computing Ultra-low R : 6.6m typical DS(on) and ultra-dense embedded computing boards where high- True 7A current capability current low-voltage rails from sub-1V to 5.5V have to be Power rail switching from sub-1V to 5.5V sectioned. The integrated 6.6m R N-channel DS(ON) Bias voltage form 2.7V to 9V MOSFET ensures low voltage drop and low power dissipation while delivering up to 7A of load current. 1A OFF-state bias supply current 1A OFF-state power switch leakage current The MIC95410 is internally powered by a separated bias Adjustable slew rate for inrush current limiting by voltage from 2.7V to 9V. It includes a TTL-logic level to external capacitor gate a voltage translator driving a charge pump, and an output discharge function when disabled. The OFF-state Load discharge current from bias supply (VS) and the power switch OFF- TTL-compatible control input state leakage current (I ) are both below 1A. OFF 10-pin 1.2mm 2.0mm QFN package, 0.5mm pin pitch The MIC95410 provides user-adjustable slew-rate- 40C to +125C junction temperature range controlled turn-on to limit the inrush current to the input supply voltage. Applications The MIC95410 is available in a thermally efficient, space- Embedded computing boards saving 10-pin 1.2mm x 2.0mm QFN package with 0.5mm Servers pin pitch and an operating junction temperature range from Data storage equipment 40C to +125C.
