ATS671LSE Specification  
Preliminary – Subject to Change  
Self Calibrating TPOS Gear Tooth Sensor with  
Pin Out Diagram  
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.  
Pin 1: VCC  
Pin 2: VOUT  
Pin 3: Test Pin (Tie to GND)  
Pin 4: Gnd  
The ATS671LSE-LT sensor system is optimized for cam  
applications and is available with or without the TPOS function
