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.
