The ADP194 is a high-side load switch designed for operation
from 1.1 V to 3.6 V and is protected against reverse current flow
from output to input. 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 load current and minimizes power loss.
The low 2 μA (maximum) ground current and ultralow shut-
down current make the ADP194 ideal for battery-operated
High-Side Power Switch
TYPICAL APPLICATIONS CIRCUIT
portable equipment. The built-in level shifter in the enable logic
input makes the ADP194 compatible with modern processors
and GPIO controllers.
Beyond operating performance, the ADP194 occupies minimal
printed circuit board (PCB) space with an area of less than
0.64 mm2 and a height of 0.50 mm. The ADP194 is available in
an ultrasmall 0.8 mm × 0.8 mm, 4-ball, 0.4 mm pitch WLCSP.
