Texas Instruments TPS65982DMC Dock Management Controller
Texas Instruments TPS65982DMC Dock Management Controller is for docks, hubs, and monitors implementing TI PD controllers. The TPS65982DMC includes a USB Low-Speed endpoint capable of receiving firmware updates for the system's PD controllers. The firmware update is performed securely using SHA-256 and RSA-3072 authentication. Also, the endpoint provides USB billboard functionality. The TPS65982DMC integrates back-to-back NFET drivers to control the system power supply from an external adapter. The DMC monitors the current through the adapter input path and other system points and adjusts the power advertisement of managed PD controllers to ensure the external adapter is not overloaded. When included in USB4 systems, the Texas Instruments TPS65982DMC monitors the upstream-facing port's connection state and updates the downstream-facing ports' connection state to ensure consistent data behavior across the system.
