ATS616LSG is a peak-detecting gear tooth sensor produced by Allegro. It has self-calibration, first-tooth detection, immunity to air gap variation and system offsets, elimination of signature tooth offsets, extremely low timing-accuracy drift with temperature changes, large air gap capability, small integrated package, optimized magnetic circuit, undervoltage lockout (UVLO) and wide operating voltage range.
The ATS616LSG sensor provides accurate gear‑edge detection at low speeds using a dual‑element Hall IC, integrated capacitor, and automatic gain control. It is supplied in a 4‑pin SIP package with a lead‑free, matte‑tin plated leadframe.
The datasheet includes electrical and performance specifications, thermal characteristics, EMC test references, and mechanical information for designers integrating the sensor into automotive camshaft or other gear‑tooth applications.
