ROHM BA6209N, BA6209 Datasheet

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

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.

R.

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.
