General Description
EC301 is an USB Type-C controller (USB Type-C™ Specification 1.1) with and without internal PMOS FET.
It is specially designed for power adapter and charger applications (*up to 3A @5V).
It negotiates with the UFP devices according to USB Type-C specifications.
Once EC301/EC302 identifies the UFP devices as USB Type-C compliant, it will provide the current rating information accordingly.
It also prevents the VBUS from being asserted unless a valid connection has been detected.EC301 is a USB Type-C DFP CC controller chip with intelligent identification function.
USB Type-C chip supports V1.1 port protocol connection detection, identification, DFP radio equipment and inserted current configuration, only in the adapter (DFP) to open the power supply to the VBUS detection after UFP insertion, when UFP pulled out, will automatically shut down VBUS.
Widely used in car charger, charger,charging, mobile power etc.
