ZHCSIY2B July 2018 – August 2021 TPS65988
PRODUCTION DATA
Figure 8-1 shows the USB PD physical layer block surrounded by a simplified version of the analog plug and orientation detection block. This block is duplicated for the second TPS65988 port.
USB-PD messages are transmitted in a USB Type-C system using a BMC signaling. The BMC signal is output on the same pin (Cx_CC1 or Cx_CC2) that is DC biased due to the DFP (or UFP) cable attach mechanism discussed in the Cable Plug and Orientation Detection section.
