BA6235F
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.
FApplications
3V radio cassette tape recorders
Micro-cassette tape recorders
FFeatures
1) Wide range of operating voltage. (1.8 X 5V)
2) Low current consumption. (IQ = 2.0mA)
3) Various DC motors can be driven by changing the ex-
ternal CR time constants.
FAbsolute maximum ratings (Ta = 25_C)
FRecommended operating conditions (Ta = 25_C)
