Allegro MicroSystems Special Purpose & E-Motor Speed Sensor ICs

Allegro MicroSystems Special Purpose and E-Motor Speed Sensor ICs offer an extensive portfolio of optimized solutions for many non-automotive applications where speed or speed and direction information are needed. Combining application and algorithm experience with OEMs, these application-specific speed sensor ICs were developed. Allegro MicroSystems Special Purpose and E-Motor Speed Sensor ICs utilize these features for their target applications, improving safety and performance.

The ATS668LSM is an optimized Hall-effect integrated circuit (IC) and permanent magnet pellet combination with integrated EMC protection components to provide a user-friendly solution for true zero-speed digital gear tooth sensing.

The ATS17501 is a single IC solution designed for rotational position sensing of a ferrous gear target found in automotive and industrial electric motor applications.

The A17301 integrates a single IC and EMC components into a small SIP package, providing a robust and cost-effective solution for digital ring-magnet sensing or ferromagnetic target sensing when coupled with a back-biasing magnet.
