BA6220 General use electronic governor

Motor driver ICs General use electronic governor 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 wit.
