BLDC Motor Control Kit with ATA6833/ATA6834
The application board is ready to run when connected to 12V at connector X1 on the Basis
Board. The Basis Board and Controller Board must be connected to each other via connector
X5 on both boards.
The board can be connected to the automotive environment over LIN bus by the LIN clamp.
There is no LIN protocol handler implemented in the microcontroller. A touch-screen display
on the Controller Board acts as the user interface. To the application board running, the follow-
ing two steps need to be done:
Figure 7-1.
Controller Board
1. Jumper J1 on the Controller Board should be placed to supply the display. After this
2. The application system needs to be woken up. For this purpose, push the button S1.

interaction with the resistive touch panel is possible. If this is not done, the display
remains dark and the VCC current demand is only the demand of the Hall sensors.
The microcontroller and BLDC operation can also run without J1. In this case, inter-
action with the panel is possible; however, the touch panel works only resistively.
