Through integrating the logic needed to negotiate configuration control, both devices are able to operate as a downstream facing port (DFP), or source; an upstream facing port (UFP), or sink, or as a dual role port (DRP) able to both source and sink data and power.
The CC1 and CC2 pins are a feature of the Type-C connector and allow hosts, hubs and peripherals to determine the presence of a device, the orientation of the connector, as well as if and how power will be supplied between devices.
Support for the CC logic feature provided by these new controllers delivers what many consumers are now keen to experience—the ability to share power and data between devices with a single cable, whatever its orientation.
“The success of USB Type-C is thanks to manufacturers like Diodes Incorporated growing the ecosystem,” said Jeff Ravencraft, President and COO, USB-IF. “Engineers and manufacturers alike benefit from new, innovative products.”
“We are pleased to enhance our USB Type-C offering with these two devices with a higher level of integration in a small footprint,” said Kay Annamalai, Senior Marketing Director. “With industry-leading active and standby current consumption, coupled with low insertion losses and the signal integrity needed to support data speeds of 5Gbps and 10Gbps, PI5USB30213A and PI5USB31213A will help accelerate the adoption of the Type-C connector.”
The controllers also support VBUS power up to 15 watts or VCONN power up to 2.5 watts for UFP devices, meaning upstream devices do not need to be connected to a power supply or have a battery fitted.
Their small outline and low power means they are well-suited for a wide range of applications such as portable consumer devices, as well as laptops, smart phones, networked peripherals and external storage devices.
