In reference to the 100W power carrying capacity:
That seems to me like a lot of power to be sending through a 0.5mm wide contact pin separated from the data pin by another 0.5mm. I see elsewhere that they have upped the voltage to 20V, which reduces the current required - is that all it takes?
- lsaferite 12y agoPower comes across 8 pins (4 Vbus, 4 Ground) From the spec: "3.7.7.4 Contact Current Rating (EIA 364-70, Method 2) A current of 5.0 A shall be applied collectively to VBUS pins (i.e., pins A4, A9, B4, and B9) and 1.25 A applied to the VCONN pin (i.e., B5 of the plug connector) with the return path through the corresponding GND pins (i.e., pins A1, A12, B1, and B12). A minimum current of 0.25 A shall also be applied individually to all the other contacts. When the currents are applied to the contacts, the temperature rise shall not exceed 30 °C at any point on the USB Type-C mated plug and receptacle under test, when measured at an ambient temperature of 25 °C." http://www.usb.org/developers/docs/ http://www.usb.org/developers/docs/
