FIGURE 8 - APPLICATION EXAMPLE 8
Only the TMC2005s, and eight transceivers are indicated in the above figure. Connect the other pins adequately.
Note: When connecting several TMC2005s on the same board with the open-drain outputs like Fig. 8, four
TMC2005s are maximum to connect and 5Mbps is the maximum data rate.
