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.

FEATURES

Low RDSON of 50 mΩ @ 3.3 V (WLCSP only)

Low input voltage range: 1.65 V to 6.5 V

1 A continuous operating current

Built-in level shift for control logic that can be operated by 1.2 V logic

Low 2.5 μA quiescent current @ VIN = 2.8 V

Low 1.1 μA shutdown current @ VIN = 2.8 V

Reverse current blocking

Programmable start-up time

Ultrasmall 1 mm × 1 mm, 4-ball, 0.5 mm pitch (WLCSP)

Tiny 8-lead lead frame chip scale package (LFCSP) 2.0 mm × 2.0 mm × 0.55 mm, 0.5 mm pitch

APPLICATIONS

Mobile phones

Digital cameras and audio devices

Portable and battery-powered equipment
