TUSB321AIRWBR explains

The configuration passageway that TUSB321AIRWBR parts of an apparatus can realize Type-C ecosystem place to need on USB Type-C port (CC) is logistic. TUSB321AI parts of an apparatus uses CC to bring a foot to determine the join condition of port and cable direction, and undertake the part detects control with mode of Type-C electric current. TUSB321AI parts of an apparatus can be configured for port of be issued to lower levels (DFP) , go up port (UFP) or dual role port (DRP) , because this makes the good choice of any application.

According to Type-C standard, TUSB321AIRWBR parts of an apparatus is DRP in configuration when, can alternant configuration is DFP or UFP. CC is logistic piece go up through monitoring CC1 and CC2 cite a base get on pull or next pulling resistor, when to join in order to decide the direction of USB port, cable and the part that detect. The part that CC logic reachs according to detecting will decide mode of Type-C electric current is acquiescent, medium tall still. This logic decides port to whether join below UFP and DRP mode through carrying out VBUS to detect successful.

This parts of an apparatus can work inside limits of broad power supply, and have inferior power comsumption. TUSB321AIRWBR parts of an apparatus applies to industrial level and limits of commercial class temperature.
