ATS685LSH

ATS685LSH Two-Wire, Zero Speed Differential Gear Tooth Sensor IC Features and Benefits Fully optimized differential digital gear tooth sensor IC Running Mode Lockout Unique algorithms for increased vibration immunity AGC and reference adjust circuit Air gap independent switchpoints Digital output representing gear profile Precise duty cycle throughout operating temperature range Large operating air gap range Short power-on time True zero-speed operation Undervoltage lockout (UVLO) Wide operating voltage range Internal current regulator for two-wire operation Single-chip sensing IC for high reliability Robust test coverage capability using Scan Path and IDDQ measurement Package: 4-pin SIP (suffix SH) Not to scale Description TheATS685LSH is an optimized Hall-effect sensing integrated circuit and rare-earth pellet combination that provides a user-friendly solution for true zero-speed digital gear-tooth sensing in two-wire applications. The sensor IC consists of a single-shot molded plastic package that includes a samarium cobalt pellet, a pole piece, and a Hall Effect 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 single integrated circuit incorporates a dual element Hall-effect sensor IC and signal processing circuitry that switches in response to differential magnetic signals created by ferromagnetic targets.
