Product DetailsThe ADP1290 is a high-side load switch designed for operation between 2.3 V and 13.2 V. This load switch provides power domain isolation, helping to extend battery operation. The device contains a low on-resistance, N-channel MOSFET that supports more than 2 A of continuous current and minimizes power loss. In addition, RDSON is constant independent of the VIN voltage. The low 15 ƒÊA quiescent current and ultralow shutdown current of 20 ƒÊA make the ADP1290 ideal for battery-operated portable equipment. The built-in level shifter for enable logic makes the ADP1290 compatible with many processors and general-purpose input/output (GPIO) controllers.
In addition to operating performance, the ADP1290 occupies minimal printed circuit board (PCB) space with an area of less than 1.5 mm2 and a height of 0.60 mm.
The ADP1290 is available in an ultrasmall, 1 mm × 1.5 mm, 6-ball, 0.5 mm pitch WLCSP.

Evaluation Kits (1)
ADP1290CB-EVALZ evaluation board is using the ADP1290 12V, 2A Logic Controlled High-Side Power Switch to demonstrate the functionality of the ADP1290 power switch. Simple device measurements such as VIN to VOUT resistance (RDSON), ground current, and off state current can be demonstrated 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.
