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 small 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 magnetic signals 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). Highresolution (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). The ATS672LSB ATS672LSB 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 ATS672LSB ATS672LSB sensor system is optimized for cam applications. Four versions of this device are available. The sensor can be chosen to have a high or low output signal in response to a "tooth". The sensor is also available with and without TPOS (true power on state) capability. The low-on-tooth sensor without TPOS is available through general sales. (Part # ATS672LSB-LN ATS672LSB-LN).
