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, RDS
ON
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 mm
2
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.
