... Reversible motor driver BA6219B / BA6219BFP-Y The BA6219B and BA6219BFP-Y are reversible-motor drivers suitable for brush motors. Two logic inputs allow four out- put modes: forward, reverse, idling, and braking. The motor revolving speed can be set arbitrarily by controlling the volt- age applied to the motor. ...

... There are no circuits built into these ICs that pre- vent in-rush currents. Therefore recommended to place a current limiting resistor or other physical counter- measure. BA6219B / BA6219BFP-Y (14) If the potential of the output pin sways greatly and goes below the potential of ground, the operation of the IC may malfunction or be adversely affected. In such a case, place a diode between the output and ground, or other measure, to prevent this ...
