ADP1190A Integrated 500 mA Load Switch with Quad Signal Switch
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.
