Application recommendations
Figure 44. Application diagram bridge drivers
Most motor bridge drivers use a reverse battery protection diode (D) inside the supply rail.
This diode prevents a reverse current flow back to V
disabled via the logic inputs while motor inductance still carries energy. In order to prevent a
hazardous overvoltage at circuit supply terminal (V
limit the voltage overshoot. As basic orientation, 50µF per 1A load current is recommended.
As an alternative, a Zener protection (Z) is also suitable.
Even if a reverse polarity diode is not present, it is recommended to use a capacitor or
