Self Calibrating TPOS Gear Tooth Sensor with 9Bit Signal Capture

The ATS671LSE true zero speed gear tooth sensors are optimized Hall IC/magnet configurations packaged in a Single In Line Package (SIP) that provides a user-friendly solution for digital gear tooth sensing applications. The SIP module consists of an over-molded package, which holds together a samarium cobalt magnet, a pole piece and a true zero-speed Hall IC that has been optimized to the magnetic circuit. This package can be easily assembled and used in conjunction with gears of various shapes and sizes. The sensor incorporates a single element Hall IC that switches in response to the magnetic signal created by a ferrous target. The IC contains a sophisticated digital circuit designed to eliminate the detrimental effects of magnet and system offsets. Signal processing is used to provide zero speed performance independent of air gap and also to dynamically adapt device performance to the typical operating conditions found in automotive applications (reduced vibration sensitivity). High-resolution (9-bit) peak detecting DACs are used to set the adaptive switching thresholds of the device. Hysteresis in the thresholds reduces the negative effects of any anomalies in the magnetic signal (such as magnetic overshoot) associated with the targets used in many automotive applications. The ATS671LSE also includes a low bandwidth filter that increases the noise immunity and the signal to noise ratio of the sensor. These features result in potential improvements in both the timing accuracy and the jitter performance of the device. The ATS671LSE-LT sensor system is optimized for cam applications and is available with or without the TPOS function
