Motor driver ICs Reversible motor driver BA6209 / BA6209N The BA6209 and BA6209N are reversible-motor drivers suitable for brush motors. Two logic inputs allow three output modes : forward, reverse, and braking. The motor revolving speed can be set arbitrarily by controlling the voltage applied to the motor with the control pin voltage VR. FApplications VCRs and cassette tape recorders FFeatures 1) Power transistors can handle a large current (1.6A maximally). 2) Brake is applied when stopping the motor. 3) Built-in function to absorb rush currents generated by reversing and braking. 4) Motor speed controlling pin. FBlock diagram 5) Small standby current. (VCC = 12V, IO = 5.5mA typically) 6) Stable operation during mode changes either from forward to reverse or vice v [ ... ]
