1.5 HSEC 180-pin Control Card Docking Station

The TMDSHSECDOCK 180-pin docking station is available for purchase through Texas Instruments. The docking station is a baseboard that enables rapid prototyping. There is a power switch on the docking station that determines whether power to the Control Card is supplied by the 5 V connector or the USB connector.

Note: The docking station power switch must be toggled to the EXT-ON side to meet the power requirements of the AM263x Control Card. EXT-ON indicates that the power is being sourced from the Barrell connector of the Control Card Dock. The mini-USB (USB-ON) connector does not meet the power requirements of the AM263x Control Card.

The AM263x Control Card has a power mux (TPS2121RUXT) that supplies power from the type-C connection, as long as the voltage supplied by the type-C connection is equal to or greater than the voltage supplied by the HSEC docking station. Therefore, if both a type-C connection is present and the Control Card is connected to a powered HSEC docking station, then the power mux routes the type-C supplied voltage to VMAIN of the Control Card. If there is no type-C connection and voltage is being supplied through the HSEC docking station, then the power mux routes that voltage to VMAIN of the Control Card.

For more information on the docking station, refer to the 180-Pin Docking Station Informational Guide.
