Please note: SKY84632 is being discontinued and is not recommended for new designs. The SKY84632 SmartSwitch is a slew-rate-controlled P-channel MOSFET power switch designed for high side load switching applications. This switch operates with inputs ranging from 1.5V to 5.5V, making it ideal for 1.8V, 3V and 5V systems. It connects/disconnects up to 3A continuous loads powered from the DC power rail with stringent off-state current targets and high load capacitances (up to 100μF) through enable control. The integrated low-impedance PMOSFET switch, together with typical 2.7ms turn-on slew rate control, prevents large inrush current and excessive voltage drop on power rails. The SKY84632 has the reverse blocking feature that blocks unexpected reverse current from OUT to IN during the PMOSFET on and off states. The typical 9μA quiescent current makes it ideal for power saving applications. The exceptional low off-state current drain (maximum 1μA) facilitates compliance with standby power requirements. The switch enable control is active high with an internal pull-down resistor that eliminates the need for an external pull-down resistor. The SKY84632 also includes over-temperature protection and recovers automatically when the fault is removed. The SKY84632 is available in a 6-bump, 1.0mm x 1.5mm, Wafer-Level Chip-Scale Package (WLCSP) and is rated over the -40°C to +85°C temperature range.
