Circuit operation
(1)
The signal from the Hall device is amplified by the
Hall amplifier and then supplied to the driver circuit. The
driver gain, which is constant, is regulated by changing
the Hall amplifier gain with the input current on the output
current control pin (E
CI
pin). The motor rotational speed
is sensed by the FG, and the output of which is F / I-con-
verted and supplied to the E
CI
pin as a feedback signal,
so that a constant rotational speed is maintained as fol-
lows :
(
1) The motor speed decreases.
(
2) The speed control IC outputs a feedback signal to the
ECI pin.
(
3) The Hall amplifier gain increases.
(
4) The output current increases.
(
5) The motor speed increases.
