Manufacturer description

The 16U2 USB charge control IC — part of the family technicians call U2, Tristar or Tigris depending on generation. This chip sits between the Lightning or USB-C port and the rest of the power system, negotiating what is plugged in and whether to accept charge. When it fails the phone will not charge, charges only sometimes, reports "accessory not supported", or gets warm around the port with nothing plugged in. It is a common failure because it is the first thing exposed to a bad cable, a surge, or liquid at the port — which is exactly why it is worth replacing before condemning a board. • Restores charging when the charge control IC has failed • Surface-mount part — requires hot air and micro-soldering • Replacement chip for chip-level repair Compatible with: iPhone logic boards — confirm the marking on your board before ordering.
