Crankshaft Sensor ICs

Allegro’s portfolio of crankshaft sensor ICs is well suited to meet the applications needs for speed-only and direction detection requirements. Allegro was the first to market with Hall-effect crankshaft sensor ICs with direction detection (a required component for start-stop engine technologies), and leads the way in market performance for both speed-only and direction detection crankshaft sensor ICs.

Allegro sensor ICs are available in the Gear-Tooth Sensor (GTS) package with integrated back-biasing magnet for ease of implementation and high performance with a ferrous metal target; as well as in SIP package offerings with and without integrated bypass capacitors, for use with encoded ring magnet targets.
