ADP198 is a logic controlled, 1A, high-side load switch with reverse current blocking. This data sheet provides detailed information about the product, including features, applications, and typical circuits.
The ADP198 high‑side load switch operates from 1.65 V to 6.5 V and provides reverse‑current protection, making it suitable for battery‑powered portable equipment such as mobile phones and digital cameras. It features a low on‑resistance P‑channel MOSFET, ultra‑low quiescent and shutdown currents, and a built‑in level shifter for 1.2 V logic enable signals.
Two package options are available: an ultra‑small 1 mm × 1 mm 4‑ball WLCSP and an 8‑lead 2 mm × 2 mm × 0.55 mm LFCSP. The device supports programmable turn‑on delay times to control inrush current and includes thermal data for proper board design.
