BA6220
The BA6220 is a monolithic IC designed for controlling the speed of general-purpose DC motors.
The IC consists of a reference
voltage generator, current multiplier, comparator, and start-up circuit.
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 constants.
A large power dissipation is allowed by grounding the pin connected with the IC substrate.
