3.6 V, 500 mA Logic Controlled High-Side Load Switch Data Sheet ADP199 FEATURES GENERAL DESCRIPTION Constant low RDS of 40 m over input voltage range The ADP199 is a high-side load switch designed for opera- ON Low input voltage range: 0.9 V to 3.6 V tion between 0.9 V to 3.6 V. A load switch provides power 500 mA continuous operating current at 85C domain isolation, thereby helping to keep subsystems isolated 1.2 V logic compatible enable input and powered independently, and enabling reduced power Low 6 A quiescent current, independent of load current consumption. Ultralow shutdown current: <100 nA The ADP199 contains a low on-resistance, N-channel MOSFET Ultrasmall 0.8 mm 0.8 mm 0.5 mm, 4-ball, to minimize power loss, and supports over 500 mA of continuous 0.4 mm pitch WLCSP load current. The low 6 A quiescent current and ultralow shutdown current make the ADP199 ideal for battery-operated APPLICATIONS portable equipment. The built-in level shifter for enable logic Low operating voltage processors makes the ADP199 compatible with many processors and GPIO Mobile phones controllers. Digital cameras and audio devices Portable and battery-powered equipment In addition to high performance, the ADP199 occupies mini- Optical XMT/RCVR modules mal printed circuit board (PCB) space with an area of less than 2 0.64 mm and a height of 0.50 mm. The ADP199 is available in an ultra-small, 0.8 mm 0.8 mm 0.5 mm, 4-ball, 0.4 mm pitch WLCSP.
