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
area less than 1.92 mm2 and a height of 0.50 mm. The ADP1190
is available in an ultrasmall 1.2 mm × 1.6 mm, 12-ball, 0.4 mm
pitch WLCSP.
