Allegro MicroSystems, LLC (Worcester, MA) introduced an addition to its camshaft sensor family of products. As a single element, non-TPOS sensor it provides first falling edge detection, high running-mode edge accuracy, and direction/orientation insensitivity over the full operating range of air gap, speed, and temperature. Allegro’s ATS601LSG is a true zero-speed gear tooth sensor IC consisting of an optimized Hall IC and simple magnetic pellet configuration for phased cam, start/stop engine applications. The single element Hall IC and magnet configuration switches in response to magnetic signals created by a ferrous target. Features include:
- A low bandwidth filter that increases the noise immunity and the signal-to-noise ratio of the sensor.
- A sophisticated digital circuit design to eliminate the detrimental effects of target geometry discontinuity, magnet and system offsets, and thermal gradients.
- Signal processing to achieve speed performance independent of air gap.
