... ATS612LSG DYNAMIC, SELF-CALIBRATING, PEAK-DETECTING, DIFFERENTIAL HALL-EFFECT GEAR-TOOTH SENSOR The ATS612LSG gear-tooth sensor is a peak-detecting device that uses automatic gain control to provide extremely accurate gear edge detection down to low operating speeds. Each sensor module consists of an over-molded package, which holds together a samarium-cobalt magnet, a pole piece and a differential open- collector Hall IC that has been optimized to the magnetic circuit ...

... The peak signal of every tooth and valley is detected by the filter and is used to provide an instant reference for the operate and release point Page ATS612LSG comparator. In this manner, the thresholds are adapted and referenced to individual signal peaks and valleys, providing immunity to zero line variation from installation ...

... LOW transition. Under-Voltage Lockout. When the supply voltage is below the minimum operating voltage (V Page ATS612LSG device is OFF and stays OFF irrespective of the state of the magnetic field. This prevents false signals, which may be caused by under-voltage conditions (especially during turn on), from appearing at the output. ...
