描述 Description

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.●

特性 Features

1) Wide range of operating voltage. (3.5~16V)
2) Large starting torque at low supply voltage.
3) Large power dissipation allowable by using the PCB as a heat sink.
4) Various DC motors can be driven by changing the external constants.● Applications
   Radio cassette tape recorders
