is a single-digital-output Hall-effect Sensor
for high temperature operation. The device includes an on-chip Hall voltage generator for magnetic sensing, an amplifier to amplify Hall voltage, and a Comparator
to provide switching hysteresis for noise rejection, and an open-collector output pre-driver. An internal band-gap Regulator
is used to provide temperature compensated supply voltage for internal Circuits
and allows a wide operating supply range. While the magnetic flux density (B) is larger than threshold Bop, the OUT pin turns on (low). If B removed toward Brp, the OUT pin is latched ?on? state prior to B < Brp. When B < Brp, the OUT pin go into ? off ? state.
