4 Application information
Figure 33. Typical application schematic
Note: Mostly motor bridge drivers use a reverse battery protection diode (D) inside supply rail.
This diode prevents a reverse current flow back to Vbatt in case the bridge gets disabled via
the logic inputs while motor inductance still carries energy. In order to prevent a hazardous
overvoltage at circuit supply terminal (Vcc), a blocking capacitor (C) is needed to limit the
voltage overshoot. As basic orientation, 50μF per 1A load current in recommended. In
alternative, also a Zener protection (Z) is suitable. Even if a reverse polarity diode is not
present, it is recommended to use a capacitor or zener at Vcc because a similar problem
appears in case supply terminal of the module has intermittent electrical contact to the
battery or gets disconnected while motor is operating.
