General Description

OH443 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. While the magnetic flux

density (B) is larger than threshold Bop, the OUT pin turns on (low). When B < Brp,

the OUT pin go into “ off ” state.
