resistor.
Pay
attention
to
wattage because large current
is present.
Take a measure against Vcc
voltage rise due to reverse
connection of power supply
and back electromotive force.
This is an open collector
output. Connect a pull-up
resistor.
Set according to the amplitude
of hall element output and hall
input voltage range.
RNF

low-pass filter.
Output power Tr is equipped
externally.
High
