GENERAL DESCRIPTION

The ADP199 is a high-side load switch designed for opera-

tion between 0.9 V to 3.6 V. A load switch provides power

domain isolation, thereby helping to keep subsystems isolated

and powered independently, and enabling reduced power

consumption.

The ADP199 contains a low on-resistance, N-channel MOSFET

to minimize power loss, and supports over 500 mA of continuous

load current. The low 6 µA quiescent current and ultralow

shutdown current make the ADP199 ideal for battery-operated

portable equipment. The built-in level shifter for enable logic

makes the ADP199 compatible with many processors and GPIO

controllers.

In addition to high performance, the ADP199 occupies mini-

mal printed circuit board (PCB) space with an area of less than

0.64 mm

and a height of 0.50 mm.

The ADP199 is available in an ultra-small, 0.8 mm × 0.8 mm ×

0.5 mm, 4-ball, 0.4 mm pitch WLCSP.

Data Sheet ADP199 THEORY OF OPERATION The ADP199 is a high-side NMOS load switch controlled by an internal charge pump. The ADP199 is designed to operate with power supply voltages between 0.9 V and 3.6 V. An internal charge pump biases the NMOS switch to achieve a relatively constant, ultralow on resistance of 40 mΩ across the entire input voltage range. The use of the internal charge pump also allows for controlled turn-on times.
