This is an open collector
output. Connect a pull-up
resistor.
Current limit setting resistor.
Use a larger resistor in order to
reduce power consumption
from VREF.
Minimum rotating speed and
full
torque
time
during
restarting can be set.
Speed control depending on
ambient
temperature
is
enabled by thermistor.
RNF
voltage
smoothing
low-pass filter.
Take a measure against Vcc
voltage rise due to reverse
connection of power supply
and back electromotive force.
Output power Tr is equipped
externally.
High
voltage
application is also allowed.
Output
current
detecting
resistor.
Pay
attention
to
wattage because large current
is present.
Simultaneous ON prevention
time can be set.
Set according to the amplitude
of hall element output and hall
input voltage range.
REG：Internal reference voltage OSC：Oscillation circuit REF：Reference voltage generating circuit
TSD：Thermal shutdown(heat rejection circuit)
