Allegro MicroSystems Inc. Self Calibrating Differential Gear Tooth Sensor ATS616LSGTN-T

The ATS616LSG is a dynamic self-calibrating peak-detecting differential Hall-effect gear tooth sensor IC designed for accurate edge detection in gear-based speed, position, and timing systems, including automotive camshaft sensing. It is housed in a 4-pin SIP package with a Pb-free, 100% matte tin plated leadframe. The device operates from a supply voltage of 3.5 to 24 V, with an operating ambient temperature range of -40 to 150 °C and a maximum junction temperature of 165 °C. It supports an operating air gap range of 0.4 to 2.5 mm and a maximum operating frequency of 10,000 Hz. The IC incorporates integrated peak and valley detection, eliminating the need for external capacitors, and maintains low timing-accuracy drift with temperature changes.
