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.

FUNCTIONAL BLOCK DIAGRAM
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.
