GENERAL DESCRIPTION

The ADP196 is a high-side load switch designed for operation from 1.8 V to 5.5 V. This load switch provides power domain isolation, helping to extend battery operation. The device contains a low on-resistance, N-channel MOSFET that supports more than 3 A of continuous current and minimizes power loss. In addition, RDSON is constant, independent of the VIN voltage. The low 25 μA quiescent current and ultralow shutdown current make the ADP196 ideal for battery-powered portable equipment. The built-in level shifter for enable logic makes the ADP196 compatible with many processors and GPIO controllers.
