SLVSER3A November 2018 – April 2020 TPS65982BB
PRODUCTION DATA.
The TPS65982BB is a USB billboard controller for USB Type-C systems. The integrated USB2 data multiplexer allows the billboard controller to be switched between two USB Type-C ports or allows a USB2 device controller to be passed through to the ports.
The TPS65982BB includes an integrated 5V load switch that may be used to supply VBUS power to an additional USB Type-A receptacle. See the Port-Power Switches section for a high-level block diagram of the port power switch, a description of the features, and more detailed circuitry.
The port-data multiplexer connects various input pairs to the system port through the PA_USB_P, PA_USB_N, PB_USB_P, PB_USB_N pins. For a high-level block diagram of the port-data multiplexer, a description of the features, and more detailed circuitry, refer to the USB Port-Data Multiplexer section.
The power-management circuitry receives and provides power to the TPS65982BB internal circuitry and to the VOUT_3V3 and LDO_3V3 outputs. See the Power Management section for a high-level block diagram of the power management circuitry, a description of the features, and more detailed circuitry.
The digital core provides the engine for handling control of all other TPS65982BB functionality. A portion of the digital core contains ROM memory which contains all the firmware required to execute USB billboard behavior. In addition, a section of the ROM, called boot code, is capable of initializing the TPS65982BB device, loading of device configuration information, and loading any code patches into volatile memory in the digital core. See the Digital Core section for a description of the features, and more detailed circuitry.
The TPS65982BB is an I2C slave to be controlled by a host processor (see the I2C Slave Interface section), and an SPI master to write to and read from an optional external flash memory (see the SPI Master Interface section).
The TPS65982BB device also integrates a thermal shutdown mechanism (see the Thermal Shutdown section) and runs off of accurate clocks provided by the integrated oscillators (see the Oscillators section).
