●Application circuit example(Constant values are for reference)

Substrate design note

a) IC power, motor outputs, and motor ground lines are made as fat as possible.

b) IC ground (signal ground) line is common with the application ground except motor ground (i.e. hall ground etc.),

and arranged near to (–) land.

c) The bypass capacitor and/or Zenner diode are arrangement near to Vcc terminal.

d) H+ and H– lines are arranged side by side and made from the hall element to IC as shorter as possible,

because it is easy for the noise to influence the hall lines.

Take a measure against Vcc voltage

rise generated by reverse connection

of current and back electromotive

force.

a

pull-up

resistor

is set.

Set according to the amplitude

of hall element output and hall

input voltage range.
