BA6209N ROHM

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. Applications VCRs and cassette tape recorders Features 1) Power transistors can handle a large current 5) Small standby current. (1.6A maximally). (VCC = 12V, IO = 5.5mA typically) 2) Brake is applied when stopping the motor. 6) Stable operation during mode changes either from 3) Built-in function to absorb rush currents generated by forward to reverse or vice versa. reversing and braking. 7) Interface with CMOS devices. 4) Motor speed controlling pin.
