3V电子调速器 3V electronic governor
3V electronic governor
The F 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
