Original Apple iPad 8th Gen 10.2″ (2020) Main Power Management IC Chip 343S00283-A0

The Silicon Mitus SM5414W Charging IC is a premium, high-efficiency synchronous switching charger integrated circuit designed for advanced 1-cell Li-Ion battery management in modern smartphones. Operating as a critical power subsystem controller, this high-performance chip handles charging currents up to 2.5A. It utilizes intelligent power-path management, allowing a mobile device to run system operations directly from the USB input source even if the battery is fully drained or chemically dead—eliminating the waiting time required by basic trickle-charge designs.
