The device includes an on-chip Hall voltage generator for magnetic sensing, an amplifier which amplifies the Hall voltage, a Schmitt trigger to provide switching hysteresis for noise rejection, and an open-collector output.
In the presence of a magnetic flux density higher than the operating- point threshold, the output is turned on. The output state is maintained until the magnetic flux falls below the release-point threshold.
