GENERAL DESCRIPTION

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

is available in an ultrasmall 1.2 mm × 1.6 mm × 0.5 mm, 12-ball,

0.4 mm pitch WLCSP.
