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.

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.
