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 V
R.
Applications
VCRs and cassette tape recorders
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.
(V
CC = 12V, IO = 5.5mA typically)
6) Stable operation during mode changes either from
forward to reverse or vice versa.
7) Interface with CMOS devices.
