The LH223 is a unipolar ha ll switch
designed in CMOS technology. The IC
internally includes a voltage regulator, Hall
sensor with dynamic offset cancellation
system, Schmitt trigger and an open-drain
output driver.
While the magnetic flux density(B) is larger
than operate point(Bop),the output will be
turned on(low),the output is held until the
magnetic flux density(B) is lower than
release point(Brp),then turn off.
It has wide operating voltage range and
extended choice of temperature range, it is
quite suitable for use in automotive,
industrial and consumer applications.
