TSZ22111 • 15 • 001 www.rohm.com 5.6 CC_PHY 5.6.1 Outline CC_PHY has below functions of USB Type-C. (Refer to USB Type-C Spec) - Defining Port Mode > DFP Mode Condition > UFP Mode Condition > DRP Mode Condition - DFP-to-UFP Attach / Detach Detection - Plug Orientation / Cable Twist Detection - USB Type-C VBUS Current Detection and Usage - VCONN (Supply for SOP’) Control - Base-Band Power Delivery Communication (BBPD communication) - Discovery and Configuration of Functional Extensions Figure 5-3. CC_PHY Block Diagram [PORT_CONT] This block chose the port mode according to the setting from MCU. (DFP) Variable current source is connected to CC terminal. These currents of each mode are 80 μA±20%: Default Current, 180 μA±8%: Medium Current and 330μA±8%: High Current. (UFP) Pull-down resistor (Rd=5.1k Ω±10%) is connected to CC terminal. (DRP) Changing DFP and UFP is repeated frequently. [CC_DET] CC_DET has functions of “Attach / Detach Detection”, “Plug Orientation / Cable Twist Detection”, “Discovery and detect extension mode” and “USB Type-C VBUS Current Detection”. Attach / Detach is detected with monitoring voltage of CC terminal. When the voltage of CC terminal become under a threshold voltage at DFP, attach is detected. Oppositely, when the voltage of CC terminal become over a threshold voltage, detach is detected. When the voltage of CC terminal become over a threshold voltage at UFP, attach is detected.
