Product Descriptions

The HUSB266 is designed for Dual USB Type-C port applications. It supports USB DRP and PD protocols on both USB Type-C ports. Each port can be independently configured as a DRP or sink, with integrated dead battery support. Full compliance with USB PD Specification Revision 3.1, Version 2.3 is implemented.Additionally, the Port B implements DPDM charging protocols for both source and sink operations. It supports multiple fast charging protocols including QC2.0/3.0/3+, AFC, FCP, SCP, UFCS and divider 3 mode, delivering comprehensive compatibility with legacy charging devices.The HUSB266 integrates a gate driver that could be employed to enable or disable a dedicated power path.Integrated high-voltage tolerance and robust protections on CC1, CC2, D+, and D- pins enhance system reliability.
