Buy CD3217B13 Big Dot USB-C Charging IC for MacBook Air, MacBook Pro & iPad Pro | BilalGSM Pakistan
PKR 4000.00
The CD3217B13 Big Dot acts as a gatekeeper between the USB-C charger and the logic board. It negotiates charging voltages, controls power delivery, and manages USB-C data routing. When this IC fails, the communication process between the charger and device breaks down, preventing proper voltage negotiation and leaving the device unable to charge or power on.
This IC is commonly replaced during motherboard-level repairs involving charging failures, USB-C port faults, no-power conditions, and liquid damage-related issues.
Key Features
USB-C Power Delivery Controller: Manages communication between the charger and device.
Advanced Power Management: Controls charging circuits and distributes power throughout the motherboard.
USB Multiplexer (MUX): Handles USB-C signal routing and data communication.
Original Big Dot Variant: Specifically designed for boards requiring the CD3217B13 Big Dot version.
Apple Silicon Compatible: Widely used in M1, M2, and M3 generation Apple devices.
Professional BGA Package: Suitable for advanced microsoldering and board-level repair work.

Common Fault Symptoms
A faulty CD3217B13 Big Dot IC may cause:
Device stuck at 5V charging only
Current draw remaining at 0.00A to 0.04A
Failure to negotiate 15V or 20V charging profiles
No charging detected
MacBook or iPad not powering on
USB-C port not responding
One USB-C port functioning while another remains dead
Intermittent charging and power issues
Liquid damage-related charging faults
Important Repair Note
The Big Dot and Small Dot versions are NOT interchangeable.
The "dot" refers to the laser-marked orientation indicator located on the corner of the chip package. Apple uses different internal OTP memory configurations, firmware revisions, and hardware steppings between the Big Dot and Small Dot variants.
Always inspect the original IC under a microscope before replacement. Installing a Small Dot IC on a board that requires a Big Dot version may result in firmware incompatibility, charging failure, 5V-only behavior, boot issues, or complete no-power conditions.
