Motor Control Shield with BTN8982TA
for Arduino
Users Manual 6 V0.9, 2015-03
1.3 Block diagram of a bi-directional Motor Control
1
As a starting point for the Motor Control Shield, the application block diagram shown in Figure 3 was used.
2
For simplicity reasons the conductivity L
1
was removed in the Shield schematics. In the application block
3
diagram the INH pins of both half-bridges are connected to one IO-port of the microcontroller. To be more
4
flexible in the usage of the Motor Control Shield each INH of the two half-bridges is connected to a separate
5
IO pin.
