Logic Controlled, High-Side Power Switch

Analog Devices' ADP190 is a high-side load switch designed for operation from 1.2 V to 3.6 V. This load switch provides power domain isolation for extended power battery life. The device contains 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 ideal for battery-operated portable equipment. The built-in level shifter for enable logic makes the ADP190 compatible with modern processors and GPIO controllers.

Among its applications are mobile phones, digital cameras and audio devices, and portable and battery-powered equipment

With an area less than 0.64 mm² and a height of 0.60 mm. It is available in an ultra-small 0.8 mm × 0.8 mm, 4-ball, 0.4 mm pitch WLCSP.
