USB-C and BC1.2 - can you still support BC1.2 capable devices with USB-C?

Jacob Wyrick

Hi team,

Per the subject, there's a bit of confusion regarding USB-C's support for BC1.2 systems that I need help with. I understand that USB-C can support USB2.0/USB3.1 interfaces and USB-PD applications where enabled.

From what I can see, USB-C should fully remove the need for BC1.2. However, what if you plug a BC1.2 device into a USB-C port?

Is there a recommended way to support BC1.2 legacy charging applications using USB-C?

Any devices that can do this?

Thanks,

Jacob

Hi Jacob,

Sorry for the delay, our group deals mainly with high speed data, and do not focus much on power delivery. I'm going to forward this to the PD team, who should have more insight into this question.

Regards,

Nicholaus
