Controllers FAQ

How does the USB5916C handle USB Type-C attachment detection?

The device uses C_ATTACH pins to indicate valid USB Type-C attachment. When a connection is detected, the hub enables the corresponding USB 3.1 Gen 1 PHY; otherwise, the PHY remains disabled to save power.

What battery charging standards are supported?

The USB5916C supports USB-IF Battery Charging Revision 1.2, including DCP, CDP, and SDP profiles, as well as Apple portable product charger emulation and Chinese YD/T standards.

Can the USB 3.1 Gen 1 and USB 2.0 portions of ports operate independently?

Yes, the Port Split feature allows USB 3.1 Gen 1 and USB 2.0 portions of downstream ports 4 and 5 to operate independently, enumerating two separate devices in parallel for custom applications.
