GENERAL DESCRIPTION
The ADP190 / ADP191 are high-side load switches designed for
operation from 1.1 V to 3.6 V. These load switchs provide power
domain isolation for extended power battery life. The devices
contain a low on-resistance P-channel MOSFET that supports
more than 500 mA of continuous current and minimizes power
loss. The low 2 μA (maximum) of ground current and ultralow
shutdown current make the ADP190 / ADP191 ideal for battery-
operated portable equipment. The built-in level shifter for enable
logic makes the ADP190 / 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.
Beyond operating performance, the ADP190 / ADP191 occupy
minimal printed circuit board (PCB) space with an area less than
0.64 mm 2 and a height of 0.60 mm. It is available in an ultrasmall
0.8 mm × 0.8 mm, 4-ball, 0.4 mm pitch WLCSP.
