GENERAL DESCRIPTION

The ADP195 is a high-side load switch designed for operation

between 1.1 V to 3.6 V and protected against reverse current

flow from output to input. This load switch provides power

domain isolation helping extended power domain isolation. The

device contains a low on-resistance, P-channel MOSFET that

supports over 1.1 A of continuous current and minimizes power

loss. The low 1 μA of quiescent current and ultralow shutdown

current make the ADP195 ideal for battery-operated portable

equipment. The built-in level shifter for enable logic makes the

ADP195 compatible with many processors and GPIO

controllers.

In addition to operating performance, the ADP195 occupies

minimal printed circuit board (PCB) space with an area of less

It is available in an ultrasmall 1 mm × 1 mm, 4-ball, 0.5 mm

pitch WLCSP. A 6-lead 2 mm × 2 mm × 0.55 mm, 0.65 mm

pitch LFCSP is also available.
