The ADP191ACBZ-R7 is a high-side Load Switch designed for operation from 1.2 to 3.6V. This load switch provides power domain isolation for extended power battery life. The devices contain a low on-resistance P-channel MOSFET that supports more than 500mA of continuous current and minimizes power loss. The low 2μA (maximum) of ground current and ultralow shutdown current make the ADP191 ideal for battery-operated portable equipment. The built-in level shifter for enable logic makes the ADP191 compatible with modern processors and GPIO controllers. The ADP191 controls the turn-on slew rate of the switch to reduce the input inrush current. The ADP191 also incorporates an internal output discharge resistor to discharge the output capacitance when the ADP191 output is disabled.
