Block Diagram, Application Circuit and Pin Assignment
Incorporates soft switching
function. Adjust at an
optimum value because
gradient of switching of
output waveform depends
on hall element output.

Take a measure against
VCC voltage rise due to
reverse connection of power
supply and back
electromotive force.
P.9
This is an open drain
output. Connect a pull-up
resistor.
