ATS675LSE  
Self-Calibrating TPOS Speed Sensor  
Optimized for Automotive Cam Sensing Applications  
Features and Benefits  
Description  
Chopper stabilized; optimized for automotive cam  
sensing applications  
The ATS675 is the next generation of the Allegro® True  
Power-On State (TPOS) sensor family, offering improved  
accuracy compared to prior generations, gradual TPOS to  
Running Mode adjustment for accuracy-shift reduction,  
and longer output fall time for improved radiated emissions  
performance. The ATS675 provides absolute zero-speed  
performance and TPOS information.  
Optimized absolute timing accuracy step size through  
gradual transition from TPOS to Running Mode  
High immunity to signal anomalies resulting from  
magnetic overshoot and peak-to-peak field variation  
Tight timing accuracy over full operating  
temperature range  
The sensor incorporates a single-element Hall IC with an  
optimized custom magnetic circuit that switches in response  
to magnetic signals created by a ferromagnetic target. The IC  
contains a sophisticated digital circuit designed to eliminate  
the detrimental effects of magnet and system offsets. Signal  
processingisusedtoprovidedeviceperformanceatzerotarget  
speed, independent of air gap, and which adapts dynamically  
to the typical operating conditions found in automotive  
applications, particularly camshaft-sensing applications.  
True zero-speed operation  
Automatic Gain Control circuitry for air gap  
independent switchpoints  
Operation at supply voltages down to 3.3 V  
Digital output representing target profile  
Undervoltage lockout (UVLO)  
Patented Hall IC-magnet system  
Increased output fall time for improved radiated  
emissions performance  
Highresolutionpeak-detectingDACsareusedtosettheadaptive  
switching thresholds of the device, ensuring high accuracy  
despite target eccentricity. Internal hysteresis in the thresholds  
reducesthenegativeeffectsofanomaliesinthemagneticsignal  
(such as magnetic overshoot) associated with targets used in  
many automotive applications. The resulting output of the  
device is a digital representation of the ferromagnetic target  
profile. The ATS675 also includes a low bandwidth filter that  
increases the noise immunity and the signal-to-noise ratio of  
the sensor.  
Package: 4-pin SIP module (suffix SE)

The device package is lead (Pb) free, with 100% matte tin  
leadframe plating.
