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
than 1.0 mm
2
and a height of 0.60 mm.
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.
