LFCSP GENERAL DESCRIPTION The ADP198 is a high-side load switch designed for operation equipment. The built-in level shifter for enable logic makes the between 1.65 V and 6.5 V that is protected against reverse ADP198 compatible with modern processors and general-purpose current flow from output to input. A load switch provides power input/output (GPIO) controllers. The LFCSP version also allows domain isolation, thereby helping to keep subsystems isolated and the user to program the start-up time to control the inrush powered independently and enabling reduced power consumption. current at turn on. The ADP198 contains a low on-resistance P-channel MOSFET The ADP198 is available in an ultrasmall 1 mm 1 mm, 4-ball, that supports more than 1 A of continuous load current. The 0.5 mm pitch WLCSP. An 8-lead, 2 mm 2 mm 0.55 mm, low 2.5 A quiescent current and ultralow shutdown current 0.5 mm pitch LFCSP is also available. make the ADP198 ideal for battery-operated portable Rev.
