Reversible motor driver

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.

Features

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.

5) Small standby current.

(VCC= 12V, IO= 5.5mA typically)

6) Stable operation during mode changes either from forward to reverse or vice versa.

7) Interface with CMOS devices.

Applications

VCRs and cassette tape recorders
