... For brush motors Reversible motor drivers (for two motors series) BA6246, BA6246N, BA6247FP-Y, BA6239A, BA6238A, BA6238AN Overview The reversible motor driver for output 1.0A or more for two motors drives a brush motor and incorporates one and a half circuits of reversible motor driver. In addition, since the output section can control voltage applied to motors by output high voltage setting pin, the torque at the time of driving motors can be varied. ...
