Reversible motor driver

BA6950FS

The BA6950FS is a reversible-motor driver suited for brush motors. Two logic inputs allow four output modes: forward,

reverse, stop (standby), and brake. The rotational speed of motor can be set arbitrarily by changing the voltage applied

to the motor with control pins. The IC can also drive a motor at a constant speed by using a built-in current feedback

amplifier.

FFeatures

1) Two logic inputs allow four output modes: forward, re-

verse, stop (standby), and brake.

2) Motor speed variable with voltage control signals.

3) Built-in current feedback amplifier allows constant

motor speed.

4) Control gain can be set arbitrarily by using external

resistors.

5) Built-in thermal shutdown circuit.
