Repair USB-C charging and power delivery faults at board level with this CD3217B12 USB and Power Delivery IC, the Texas Instruments controller used across Apple's iPad range. This 123-pin IC manages USB-C negotiation, charging, and power delivery — when it fails, the iPad typically shows no charging, no USB connection, or refuses to power on despite a good battery and charging port.

Replacing the CD3217 is a common and effective board-level repair for iPads that have suffered charging faults, liquid damage around the USB-C circuitry, or damage from faulty chargers and cables. This is the correct 123-pin variant covering the iPad Pro 11" (2nd and 3rd Gen), iPad Pro 12.9" (4th Gen 2020 and 5th Gen 2021), iPad Air 4, iPad Air 5 (2022), and iPad Mini 6.

Common Faults Resolved

• iPad not charging with a known-good port and battery
• No USB data connection or accessory detection
• iPad dead / not powering on due to power delivery failure
• Charging faults after liquid damage around the USB-C circuit
• Damage caused by faulty third-party chargers or cables
• Intermittent charging that persists after a charging port replacement

Important Notes

• Board-level repair — microsoldering required: replacing this IC requires BGA rework equipment, hot air or infrared reflow, appropriate flux and stencils, and microsoldering experience. This is not a plug-in part and is intended for board-level repair specialists only.
• Diagnose first: confirm the CD3217 is at fault (typically via diode-mode measurements on the PD lines) before reworking, as charging faults can also stem from the port, battery, or PMIC.
• ESD-safe handling: this IC is static-sensitive — store and handle with ESD protection.
• Verify the variant: this is the 123-pin CD3217B12 — check it matches the footprint on the board being repaired before ordering.
