Buy CD3217B12 Big Dot USB-C Charging IC for MacBook Pro, MacBook Air & iPad Pro | BilalGSM Pakistan

PKR 4000.00

The CD3217B12 Big Dot acts as the primary gatekeeper of the USB-C charging system in compatible Apple devices. It communicates with the charger to negotiate the correct charging voltage, manages power flow throughout the motherboard, and controls USB-C data routing. When this IC becomes faulty, devices may fail to negotiate higher voltages, resulting in charging issues, no-power conditions, or USB-C port failures.

This chip is commonly replaced during advanced motherboard repairs involving charging faults, power issues, liquid damage, and USB-C communication failures.

Key Features

USB-C Power Delivery Controller: Handles charger communication and voltage negotiation.

Advanced Power Management: Controls charging circuits and power distribution across the logic board.

USB Multiplexer (MUX): Manages USB-C data and signal routing.

Original Big Dot Variant: Designed specifically for logic boards requiring the CD3217B12 Big Dot version.

High Reliability: Suitable for professional board-level and microsoldering repairs.

Precision BGA Package: Ideal for advanced Apple motherboard repair applications.

Important Repair Note

The Big Dot and Small Dot versions are NOT interchangeable.

The "dot" refers to the laser-marked alignment indicator located on the top corner of the IC package. Apple uses different internal firmware revisions and configurations between these variants.

Always verify the original IC marking under a microscope before replacement. Installing a Small Dot IC in place of a Big Dot version can cause charging failure, 5V-only behavior, boot issues, or complete device malfunction.
