Allegro MicroSystems Europe introduces two-wire sensor IC for ferrous targets
Designed to be user-friendly for direction detection sensing using ferrous targets, a Hall-effect integrated circuit (IC) from Allegro MicroSystems Europe combines a rare-earth pellet.
The ATS699 is a user-friendly solution for direction detection and true zero-speed, digital gear-tooth sensing, says Allegro. The small package can be easily assembled and used in conjunction with a variety of gear-tooth-sensing applications. This ATS699 IC employs patented algorithms for the special operational requirements of automotive transmission and recreational vehicle applications. It is also compatible with non-automotive applications found in white goods, exercise, and industrial equipment.
The speed and direction of the target are communicated through a variable pulse-width output protocol. According to Allegro, the ATS699 is particularly adept at handling vibration without sacrificing maximum air gap capability or creating any erroneous direction pulses. Even higher angular vibration caused by engine cranking is completely rejected by the device, adds Allegro.
The advanced vibration detection algorithm will systematically calibrate the sensor IC on the initial teeth of true target rotation and not on vibration, always guaranteeing an accurate signal in running mode. Advanced signal processing and innovative algorithms make the ATS699 particularly suitable for a range of speed and direction-sensing needs.
Allegro’s ATS699 is available in a lead (Pb) free, three-pin single in-line package (SIP) (suffix SN) package with a tin-plated leadframe.
Allegro MicroSystems develops, manufactures and markets semiconductors, offering innovative solutions for high-growth applications within the automotive market. The company also focuses on office automation, industrial, and consumer/communications solutions. Allegro is headquartered in Worcester, Massachusetts (USA) with design, applications, and sales support centres located worldwide.
