A3046 Datasheet | Allegro MicroSystems

features improved switch point stability with temperature over the A3056EU/LU. The high hysteresis of the A3058EU and A3058LU, with their excellent temperature stability, makes them especially suited to ignition timing applications where switch-point accuracy (and latching requirements) is extremely important.

Changes in fields on the magnet face caused by a moving ferrous mass are sensed by two integrated Hall transducers and are differentially amplified by on-chip electronics. The on-chip temperature pensation and Schmitt trigger circuitry minimizes shifts in effective working air gaps and switch points over temperature...
