Type c power plug12/12/2023 ![]() ![]() ![]() For example, with a hard limit of 240 W, Type C will simply not work in cases where more power is necessary. While USB Type C connectors are extremely useful in a wide range of scenarios, there are times that dedicated power delivery options are still a practical solution. For all other applications, the connector will function like any other power jack and the charging will be governed by the adapter/charging circuit. Please note that since the data transfer pins have been removed, the USB 3.0 power negotiation process does not occur, in which case the charging device will revert to the USB standard power transfer rate of 5 V and 1 A. While these are unable to be used for transferring data, they work with any standard USB Type C cable that transfers both data and power, so there are no additional steps or hardware needed by the end-user when interacting with the product. Besides the lower part cost, it reduces the complexity and failure rate by eliminating the majority of the pins and associated solder points. Thanks to the simplified design of the connector itself, with only 6 pins instead of the standard 24, the cost of the connector is significantly reduced. 24-pin Type C (left) vs 6-pin power-only Type C (right) CUI Devices’ 60 W power-only USB Type C receptacles remove the 16 data transfer pins and 2 of the ground pins, leaving only 4 power pins and 2 ground pins. The Power-Only USB Type C Connectorīecause of the benefits listed above, CUI Devices has developed power-only USB Type C receptacles for designs where charging or power delivery is the sole function. Finally, USB Type C connectors are robust with a rating of 10,000 mating cycles, ensuring a long and useful life. The standard also ensures easy design integration and Type C has a much smaller footprint than many barrel connectors. From an OEM standpoint, these connectors, both power only and data+power, are easy to find with a very stable supply chain as the standardization guarantees a certain level of interoperability. The promised convenience of utilizing a single, off-the-shelf cable type for many different products is extremely enticing to an end-user. ![]() Many new phones and mobile devices are already shipping with USB Type C, plus there is an increasing likelihood that the EU will move to adopt the Type C connector as the charging standard for all devices in the future. USB connectors have become ubiquitous and the transition to Type C is quickly gaining momentum. The largest benefit of using USB as a method of power delivery is standardization. Now with up to 240 W of power capability, USB Type C is a viable option for many applications needing significant quantities of power and can replace a standard dc power connector even when data transfer is not required. Progression of USB power levels USB Type C Benefits for Power ApplicationsĪ standard USB Type C connector houses 16 data transfer pins, 4 power pins, and 4 ground pins for a total of 24 pins. ![]()
