ADP1190:  Integrated 500mA Load Switch with Quad Signal Switch



The ADP1190 is an integrated high-side load switch with 4 signal switches designed for operation from 1.4 V to 3.6 V. This load switch provides power domain isolation for extended power battery life. The load switch is a low on-resistance P-channel MOSFET that supports up to 500 mA of continuous load current and minimizes power loss. Integrated with the load switch are 4 normally open two Ohm SPST signal switches.

Beyond operating performance, the ADP1190 occupies minimal printed circuit board (PCB) space with an area less than 1.92 mm2 and a height of 0.60 mm. The ADP1190 is available in an ultrasmall 1.2 mm × 1.6 mm, 12-ball, 0.4 mm pitch WLCSP.
