GENERAL DESCRIPTION

The ADP198 is a high-side load switch designed for operation

between 1.65 V and 6.5 V that is protected against reverse

current flow from output to input. A load switch provides power

domain isolation, thereby helping to keep subsystems isolated and

powered independently and enabling reduced power consumption.

The ADP198 contains a low on-resistance P-channel MOSFET

that supports more than 1 A of continuous load current. The

low 2.5 μA quiescent current and ultralow shutdown current

make the ADP198 ideal for battery-operated portable

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

ADP198 compatible with modern processors and general-purpose

input/output (GPIO) controllers. The LFCSP version also allows

the user to program the start-up time to control the inrush

current at turn on.

The ADP198 is available in an ultrasmall 1 mm × 1 mm, 4-ball,

0.5 mm pitch WLCSP. An 8-lead, 2 mm × 2 mm × 0.55 mm,

0.5 mm pitch LFCSP is also available.
