GENERAL DESCRIPTION The ADP190/ADP191 are high-side load switches designed for The ADP191 controls the turn-on slew rate of the switch to operation from 1.1 V to 3.6 V. These load switchs provide power reduce the input inrush current. The ADP191 also incorporates domain isolation for extended power battery life. The devices an internal output discharge resistor to discharge the output contain a low on-resistance P-channel MOSFET that supports capacitance when the ADP191 output is disabled. more than 500 mA of continuous current and minimizes power Beyond operating performance, the ADP190/ADP191 occupy loss. The low 2 A (maximum) of ground current and ultralow minimal printed circuit board (PCB) space with an area less than shutdown current make the ADP190/ADP191 ideal for battery- 2 0.64 mm and a height of 0.60 mm. It is available in an ultrasmall operated portable equipment. The built-in level shifter for enable 0.8 mm 0.8 mm, 4-ball, 0.4 mm pitch WLCSP. logic makes the ADP190/ADP191 compatible with modern processors and GPIO controllers. Rev.
