GENERAL DESCRIPTION

The 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 µA quiescent current and ultralow shutdown

current of 20 µA 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.
