GENERAL DESCRIPTION

The ADP1190 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 2 Ω SPST signal switches.

Aside from its excellent operating performance, the ADP1190

occupies minimal printed circuit board (PCB) space with an

is available in an ultrasmall 1.2 mm × 1.6 mm, 12-ball, 0.4 mm

pitch WLCSP.
