Adjust the gain according to
the characteristics of level
amplifier gain setting resistor.
Bias resistor for thermistor.
Speed control is enabled by
thermistor.
Set
the
minimum rotating
speed and full torque time in
restarting.
Output
current
detecting
resistor.
Pay
attention
to
wattage because large current
flows.
This is an open collector
output. Connect a pull-up
resistor.
Take a measure against Vcc
voltage rise due to reverse
connection of power supply.
Set according to the amplitude
of hall element output and hall
input voltage range.
RNF
voltage
smoothing
low-pass filter.
