Features and Benefits
Product DetailsThe ADP194 is a high-side load switch designed for operation from 1.1 V to 3.6 V and is protected against reverse current flow from output to input. This load switch provides power domain isolation for extended power battery life. The device contains a low on-resistance P-channel MOSFET that supports more than 500 mA of continuous load current and minimizes power loss. The low 2 μA (maximum) ground current and ultralow shutdown current makes the ADP194 ideal for battery-operated portable equipment. The built-in level shifter in the enable logic input makes the ADP194 compatible with modern processors and GPIO controllers.
Beyond operating performance, the ADP194 occupies minimal printed circuit board (PCB) space with an area less than 0.64 mm2 and a height of 0.50 mm. The ADP194 is available in an ultrasmall 0.8 mm x 0.8 mm, 4-ball, 0.4 mm pitch WLCSP.

Evaluation Kits (1)
The EVAL-ADP194 is used to demonstrate the functionality of the ADP194 power switch. Simple device measurements such as VIN to VOUT resistance (RDSON), ground current, and off state current can be demon-strated with just a single voltage supply, a voltmeter, a current meter, and load resistors.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
