Control Card Overview
2.4 HSEC 180-pin Control Card Docking Station
The
TMDSHSECDOCK 180-pin docking station
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 will be supplied by the 5V connector or USB connector.
The docking station power switch must to be toggled to the EXT-ON side to meet the power
requirements of the AM263x Control Card.
The AM263x Control Card has a power mux (TPS2121RUXT) that will supply 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 will rout 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 will route that voltage to VMAIN of the control card.

ESD protection such as wrist straps and ESD mats when interfacing with the product.
The product is used in the basic electromagnetic environment as in laboratory condition and the
applied standard will be as per EN IEC 61326-1:2021
3 Board Setup
3.1 Power Requirements
The AM263x Control Card is powered from a 5 V, 3 A USB type-C input or from a 5 V, 3 A HSEC connection
supplied by the docking station. The following sections describe the power distribution network topology that
supply the AM263x Control Card, supporting components and the reference voltages.
Power supply solutions that are compatible with the AM263x Control Card:
•
When using the USB type-C input:
– 5 V, 3 A power adapter with USB-C receptacle
– 5 V, 3 A power adapter with captive USB-C cable
– PC USB type-C port that has Power Delivery classification
•
