说明
The AWP35617 is a Type-C Configuration Channel (CC) Flippable Adapter chip with low power and high efficiency. The AWP35617 supports channel identification of USB Type-C and auto detection of different power roles based on chip settings. This chip is compatible with USB Type-C Cable and Connector Specification Release 2.5 for varies of applications.
The AWP35617 supports PIN mode and I2C mode through CTRL pin settings. SDA (INOUT1), SCL (INOUT2), INTB (OUT3) and ID pins are used to distinguish necessary functions in different control modes. The ROLE pin controls the Source (SRC) / Sink (SNK) / Dual Role Power (DRP) mode in PIN mode. The global enable signal comes from ENB pin with internal pull-up resistor for more feasibility.
The AWP35617 can determine a connection or disconnection in different power modes. The CC logic block monitors the CC1 and CC2 pins voltage to determine whether a USB port has been attached. The CC logic detects the Type-C current mode (USB Default, 1.5 A or 3.0 A) in SNK mode. VBUS detection is implemented to determine a successful attachment in SNK and DRP modes.
