This datasheet introduces the features of ATS612LSB gear tooth sensor, including automatic gain control, differential open-collector Hall IC, high-temperature plastic shell, small package, and a variety of gear shapes and sizes
The ATS612LSB is a dynamic, self-calibrating, peak-detecting, differential Hall-effect gear-tooth sensor designed for accurate edge detection. It utilizes a dual-element Hall IC with a 5-bit A/D converter that self-calibrates to minimize air-gap variations and includes a patented peak-detecting filter to eliminate offsets caused by tilt or wobble. The device is optimized for applications requiring accurate duty cycle control or edge detection, such as automotive crankshaft and transmission speed sensing.
