ATS617LSG Dynamic, Self-Calibrating, Peak-Detecting, Differential Hall Effect Gear Tooth Sensor www.datasheet4u.com Features and Benefits ▪ Self-calibrating for tight timing accuracy ▪ First-tooth detection ▪ Immunity to air gap variation and system offsets ▪ Immunity to signature tooth offsets ▪ Integrated capacitor provides analog peak and valley information ▪ Low timing-accuracy drift with temperature changes ▪ Low radiated emissions ▪ Integrated, series resistor on VCC pin for improved transient immunity ▪ Large air gap capability ▪ Small, integrated package ▪ Optimized magnetic circuit ▪ Undervoltage lockout (UVLO) ▪ Wide operating voltage range Description The ATS617 gear-tooth sensor is a peak-detecting device that uses automatic gain control and an integrated capacitor to provide extremely accurate gear edge detection down to low operating speeds. Each sensor module consists of a high-temperature plastic shell that holds together a samarium-cobalt magnet, a pole piece, and a differential opencollector Hall IC that has been optimized to the magnetic circuit. This small package can be easily assembled and used in conjunction with a wide variety of gear shapes and sizes. The gear-sensing technology used for this sensor module is Hall-effect based. The sensor incorporates a dual-element Hall IC that switches in response to differential magnetic signals created by ferrous targets. The sophisticated processing circuitry contains an A-to-D converter that selfcalibrates (no...
