3V electronic governor

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.

Features

1) Wide range of operating voltage. (1.8
5V)

2) Low current consumption. (IQ = 2.0mA)

3) Various DC motors can be driven by changing the external CR time constants.

Applications

3V radio cassette tape recorders

Micro-cassette tape recorders
