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