Lightning to USB C cable and USB C device

Hi guys,


I've been tasked with making a self-powered USB 2.0 Device with a USB C receptacle. This product should work with iOS Hosts the same way as if connected through a Lightning OTG cable aka. Cable Kit.


I guess the most common use for a Lightning to USB C cable would be to charge an iOS unit from a Mac or PC with USB C. Then the computer is the Host and the phone/pad is the Device. My need is to swap the Host/Device roles with the same cable.


After reading up on USB C the question boils down to this: Do Lightning to USB C cables relate to the pull-up/pull-down of the CC pins on the C side when they assign Host/Device roles?




Thanks,

Borge-san

hi borge-san,

afaik, you need to supply 5V VBUS to the iPhone for the charge&sync cable to initiate the connection, then you can role-swap
