Product Details

The ADP190 is a high-side load switch designed for operation from 1.2 V to 3.6 V. This load switch provides power domain isolation for extended power battery life. The device contains a low on-resistance P-channel MOSFET that supports more than 500 mA of continuous current and minimizes power loss. The low 2 μA (maximum) of ground current and ultralow shutdown current make the ADP190 ideal for battery-operated portable equipment. The built-in level shifter for enable logic makes the ADP190 compatible with modern processors and GPIO controllers.

Beyond operating performance, the ADP190 occupies minimal printed circuit board (PCB) space with an area less than 0.64 mm2 and a height of 0.60 mm. It is available in an ultrasmall 0.8 mm × 0.8 mm, 4-ball, 0.4 mm pitch WLCSP.
