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.
