Microcontroller Integration
Current Shunt
Watchdog Resistor RWD
To run the H-bridge, it is necessary to attend the Watchdog and Pace signal. To operate, a
microcontroller can be connected via the header pins X2 (see
which can be connected to the microcontroller are available on the header pins X2:
The VCC voltage level can be chosen by the jumper VMODE (see
Shunt R22 is available to monitor the H-bridge current. The sense lines AD0 and PGND (see
Table 2-2 on page
Figure 2-8.
Upper jumper RWD position 2-3 selects the standard watchdog resister value R6 33kΩ.
Optionally, the watchdog frequency can be changed via resistor R5, by setting jumper RWD to
position 1-2. Either SMD (R5A) or wired (R5B) resistors may be used.
