ADP199ACBZ

电源开关 IC - 配电 3.6V 500mA Logic Hi-Side Load Switch

GENERAL DESCRIPTION ADP199ACBZ

The ADP199 is a high-side load switch designed for operation 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.
