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.
FApplications
Radio cassette tape recorders
FFeatures
1) Wide range of operating voltage. (3.5X16V)
2) Large starting torque at low supply voltage.
