The ATS682LSH is a Hall-effect 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. This small package, with an optimized two-wire leadframe, can be easily assembled and used in conjunction with a wide variety of gear shapes and sizes.
The integrated circuit incorporates a dual-element Hall-effect circuit and signal processing that switches in response to differential magnetic signals created by ferrous gear teeth. The circuitry contains a sophisticated digital circuit that reduces magnet and system offsets, calibrates the gain for air gap independent switchpoints and provides true zero-speed operation.
Signal optimization occurs at power-up through the adjustment of offset and gain and is and is maintained throughout operation with the use of a running-mode calibration scheme. Runningmode calibration provides immunity from environmental effects such as micro-oscillations of the sensed target or sudden air gap changes.
The regulated current output is configured for two-wire interface circuitry and is ideally suited for obtaining speed information in wheel speed applications. The Hall element spacing is optimized for high resolution, small diameter targets. The package is lead (Pb) free, with 100% matte tin lead frame plating.
The ATS682 is supplied in a 4-pin SIP (suffix SH) package. The package is lead (Pb) free, with 100% matte tin lead frame plating.
