ADP1290

Data Sheet FEATURES 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 APPLICATIONS Mobile phones Digital cameras and audio devices Portable and battery-powered equipment 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. 12 V, 2 A Logic Controlled High-Side Power Switch ADP1290 TYPICAL APPLICATIONS CIRCUIT VIN + – VOUT GND ON EN OFF CHARGE PUMP LOAD 12529-001 ADP1290 Figure 1. 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.
