BA6235F
The BA6235F is an IC for controlling the speed of low voltage DC motors. It consists of a reference voltage generator,
current multiplier, and DC amplifier. The speed of DC motor is controlled by detecting the counter-electromotive force
generated by the motor. Various DC motors can be driven by changing the external CR time constants.
