The ET7301B is a programmable USB Type-Control IC. It supports the USB Type-C connector application with Configuration Channel (CC) control logic detection and indication functions. This products support a flexible hardware solution to configure DFP/UFP/DRP connection. It can connect to a controller through I2C-bus interface. ET7301B performs USB Type-C detection including attach, detach and orientation. It setup VBUS threshold detection automatically as well as the various charging current levels. ET7301B provide the software flexibility for multiple platform support.

The ET7301B integrates the physical layer of the USB BMC PD (Power Delivery) protocol to allow up to 100W of power and role swap. The BMC PD block enables full support for alternative interfaces of the Type-C specification.
