Details

Board-level parts for the newest iPhones arrive slowly, so a pre-programmed USB controller for the iPhone 17 range is a useful find for shops already seeing charging faults on it. This 121-pin chip is listed for the iPhone 17, 17 Pro and 17 Pro Max.

According to the listing, it's pre-programmed, so no charging EEPROM swap is required. The listing calls it a Tristar or U2 and puts a board position in the part number field. We couldn't confirm that position for the iPhone 17 from repair references, so check your board view.

Faults it's sold for

No charging by cable.
No connection to a computer.
Charging failure after a damaged USB-C cable.
Port damage after liquid.

Before ordering

Rule out the USB-C port, the cable and the charger, and test wireless charging to see whether the fault is limited to the cable path. Because these boards are new, schematics and board views may be limited, so confirm the part location before lifting anything.

Separate the board carefully, preheat and lift the old controller. Fit the replacement on fresh flux, rejoin and test charging and a computer connection.
