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.

FEATURES
