GENERAL DESCRIPTION
The ADP197 is a high-side load switch designed for operation
between 1.8 V and 5.5 V. This load switch provides power domain
isolation, helping extended power domain isolation. The device
contains a low on-resistance, N-channel MOSFET that supports
more than 3 A of continuous current and minimizes power loss.
The low 18 μA quiescent current and ultralow shutdown current
make the ADP197 ideal for battery-operated portable equipment.
The built-in level shifter for enable logic makes the ADP197
compatible with many processors and GPIO controllers.

PROTECTION
ADP197
Figure 1.
Overtemperature protection circuitry activates if the junction
temperature exceeds 125°C, thereby protecting itself and
downstream circuits from potential damage.
In addition to operating performance, the ADP197 occupies
minimal printed circuit board (PCB) space with an area of less
than 1.5 mm2 and a height of 0.60 mm.
The ADP197 is available in an ultrasmall, 1 mm × 1.5 mm,
6-ball, 0.5 mm pitch WLCSP.
