USB4105-GF-A Pinout

Pinout Usage and Notes

The USB4105-GF-A manages the USB Type-C interface, and its pins are used for various purposes like power delivery, data communication, and configuration. VBUS and GND handle power, while CC1 and CC2 are used for cable orientation and power delivery negotiations. The SBU pins (SBU1 and SBU2) are important for supporting alternate modes such as audio or video. The DP and DM pins are used for USB 2.0 data transfer, and VCONN provides power to active cables. Make sure to connect the pins correctly to ensure smooth data transfer and power negotiation between devices.

USB4105-GF-A Equivalent Models

Equivalent Models Usage and Notes

If you’re looking for a replacement for the USB4105-GF-A, the TUSB320 and CYPD3171 are good alternatives. Both offer similar USB 3.1 support with Type-C compatibility and Power Delivery capabilities. The TUSB320 offers faster power negotiation, while the CYPD3171 supports faster data transfer speeds (10 Gbps). The EZ-PD CCG3 also offers similar power delivery features with high efficiency. When choosing a replacement, consider the required data rate and power delivery version for your application. The 32-pin package on some models like the CYPD3171 might offer more features, but ensure compatibility with your board’s design and size limitations.

Choosing the Right USB Type-C Controller

When selecting a USB Type-C controller, it’s important to consider factors like power delivery version, data rate, and overall efficiency. The USB4105-GF-A is a great choice for most applications with its support for USB 3.1, PD 2.0, and 5 Gbps data rate. However, if you need faster data transfer or more advanced power negotiation, alternatives like the TUSB320 or CYPD3171 might be better. The TUSB320 offers quicker power negotiation, while the CYPD3171 supports a higher data rate of 10 Gbps. Always make sure the controller fits your design, both in terms of features and physical layout.
