●Product Details
●The ADP1190A is an integrated high-side load switch with four 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 four normally open, 3 Ω single pole, single throw (SPST) signal switches controlled by the charge pump.
●Beyond its excellent operating performance, the ADP1190A occupies minimal printed circuit board (PCB) space with an area less than 1.92 mm2 and a height of 0.50 mm. The ADP1190A is available in an ultrasmall 1.2 mm × 1.6 mm × 0.5 mm, 12-ball, 0.4 mm pitch WLCSP.
