GENERAL DESCRIPTION

The ADP190/ADP191 are high-side load switches designed for operation from 1.1 V to 3.6 V. These load switchs provide power domain isolation for extended power battery life. The devices contain a low on-resistance P-channel MOSFET that supports more than 500 mA of continuous current and minimizes power loss. The low 2 μA (maximum) of ground current and ultralow shutdown current make the ADP190/ADP191 ideal for batteryoperated portable equipment. The built-in level shifter for enable logic makes the ADP190/ADP191 compatible with modern processors and GPIO controllers.
