Original Texas Instruments 343S00235 U2 USB Charging IC Chip Replacement for Apple iPhone 8, 8 Plus & iPhone X

The Apple iPhone 343S00235 USB Charging IC (custom manufactured by Texas Instruments and often designated as the “U2” or “Hydra” chip by technicians) is a critical, original power-path controller found on Apple smartphone logic boards. This advanced integrated circuit plays an indispensable role in managing peripheral communication, validating accessories, and handling initial power negotiation. It is responsible for detecting when a lightning cable is plugged in, authorizing charging accessories, and regulating the direct voltage transition from the USB source into the primary charging subsystem.
