Overview

Low RDS_ON of 105 mΩ at 1.8 V
Internal output discharge resistor (ADP191)
Turn-on slew rate limiting (ADP191)
Low input voltage range: 1.2 V to 3.6 V
Ultrasmall 0.8 mm × 0.8 mm, 4-ball, 0.4 mm pitch WLCSP

Built-in level shift for control logic that can be operated by 1.2 V logic
Low 2 μA (maximum) ground current
Ultralow shutdown current: <1 μA
500 mA continuous operating current

The ADP190 / ADP191 are high-side load switches designed for operation from 1.2 V to 3.6 V. These load switches 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 mm² 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.
