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

PKR 4000.00

The CD3217B12 Small Dot USB-C Charging IC is a specialized power management and USB-C controller chip used in modern Apple MacBook Pro, MacBook Air, and iPad Pro logic boards. This critical IC manages USB Power Delivery (USB-PD) negotiation, charging control, USB-C port communication, and signal multiplexing (MUX), ensuring stable power delivery and proper device operation.

Overview

The CD3217B12 Small Dot acts as the gatekeeper of the USB-C charging system in compatible Apple devices. It negotiates charging voltages with USB-C adapters, controls power flow to the logic board, and manages USB-C data routing. When this IC becomes faulty, devices may fail to charge properly, remain stuck at 5V input, or refuse to power on altogether.

This chip is commonly replaced during motherboard-level repairs involving charging failures, USB-C port issues, liquid damage, or power-related faults.

Key Features

USB-C Power Delivery Controller: Manages voltage negotiation between the charger and device.

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

USB Multiplexing (MUX): Handles USB-C signal routing for charging and data communication.

Original Small Dot Variant: Designed to match logic boards requiring the CD3217B12 Small Dot version.

High Reliability: Suitable for professional motherboard repair and component-level servicing.

Precision BGA Package: Engineered for advanced microsoldering and board-level repairs.

Compatible Devices

Commonly found in:

• MacBook Pro A1989

• MacBook Pro A1990

• MacBook Pro A2159

• MacBook Pro A2289

• MacBook Pro A2442

• Selected MacBook Air models

• Selected iPad Pro models

Common Fault Symptoms

A defective CD3217B12 Small Dot IC may cause:

• Device stuck at 5V charging only

• No 20V USB-C power negotiation

• Charging failure

• Device not powering on

• USB-C port detection issues

• Intermittent charging behavior

• Liquid damage-related power faults

Important Repair Note

The Small Dot and Big Dot versions are not interchangeable.

The "dot" refers to the alignment mark located on the corner of the IC package. Apple uses different firmware revisions and configurations for these variants. During repair, the replacement chip must match the original dot type installed on the logic board.

Always inspect the original IC under a microscope before replacement. Installing a Big Dot IC in place of a Small Dot version may result in charging failure, boot issues, or complete device malfunction.
