ADP190 Logic Controlled, High-Side Power Switch
The 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.Mobile phones
Digital cameras and audio devices
Portable and battery-powered equipment
Beyond operating performance, the ADP190 occupies minimal
printed circuit board (PCB) space with an area less than 0.64 mm2
and a height of 0.60 mm. It is available in an ultrasmall 0.8 mm ×
0.8 mm, 4-ball, 0.4 mm pitch WLCSP.
