GENERAL DESCRIPTION The ADP1190A is an integrated high-side load switch with four Beyond its excellent operating performance, the ADP1190A signal switches designed for operation from 1.4 V to 3.6 V. This occupies minimal printed circuit board (PCB) space with an 2 load switch provides power domain isolation for extended power area less than 1.92 mm and a height of 0.50 mm. The ADP1190A battery life. The load switch is a low on-resistance P-channel is available in an ultrasmall 1.2 mm 1.6 mm 0.5 mm, 12-ball, MOSFET that supports up to 500 mA of continuous load 0.4 mm pitch WLCSP. current and minimizes power loss. Integrated with the load switch are four normally open, 3 single pole, single throw (SPST) signal switches controlled by the charge pump.
