A3144E Hall Effect Sensor


The device includes an on-chip Hall voltage generator for magnetic sensing, a comparator that amplifies the Hall voltage, and a Schmitt set off to provide switching hysteresis for noise rejection, and open-collector output. An inner bandgap regulator is used to provide temperature compensation provide voltage for internal circuits and permits a wise supply range.

If a magnetic flux density is large than threshold Bop, DO is grew to become on (low). The output is held till a magnetic flux density reversal falls under Brp inflicting DO to become off (high).
