This U2 SN2012027 +8N Q4EE EEPROM Charging IC Set gives you the exact two-chip combo needed to bring back charging and touch function on iPhone 15 and 16 series boards. The set pairs the SN2012027 U2 charging IC with a pre-programmed 8N Q4EE EEPROM chip, so you can fix a dead charging port whether the original EEPROM data is intact or already lost. Built for board-level GSM work, this set saves you a diagnostic step — install the U2 first, and only swap the EEPROM if the phone still won't wake up. A must-have for any repair bench handling iPhone 15/16 charging faults.
