This document describes the features and characteristics of the ATS616LSG-DS model, a dynamic self-calibrating peak-detecting differential Hall effect gear tooth sensor. The sensor features self-calibration, tight timing accuracy, first-tooth detection, immunity to air gap variation and system offsets, and other capabilities.
The ATS616 is a Hall-effect based gear-tooth sensor module designed to provide accurate speed and position information. It features automatic gain control and an integrated capacitor for precise edge detection down to low operating speeds, eliminating the need for external peak-holding capacitors required by previous models like the ATS612LSB.
The device incorporates a dual-element Hall IC with sophisticated processing circuitry that self-calibrates internal gain to minimize air-gap variations. It includes a patented peak-detecting filter circuit to eliminate magnet and system offsets, making it ideal for automotive camshaft sensing and other applications requiring accurate duty cycle control.
