ADP1290 12 V, 2 A Logic Controlled High-Side Power Switch
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 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.
Applications
Features and Benefits- Low RDSON of 40 mΩ
- Wide input voltage range:
2.3 V to 13.2 V - 2 A continuous operating current, TJ = <85°C
- 1.2 V logic compatible enable input
- Low 15 μA quiescent current,
VIN = 3.3 V - Low 19 μA quiescent current,
VIN = 6.5 V - Ultralow shutdown current:
2.0 μA at VIN = 6.5 V - Ultrasmall 1.0 mm × 1.5 mm, 6-ball, 0.5 mm pitch WLCSP
