ATS675LSETN-HT-T

• Product introduction

The ATS675 is Allegro® True Power State (TPOS)Sensor ICsThe next generation of the series offers more precise precision than previous generations. The ATS675 operates at absolute zero speed and provides TPOS information.

The device contains a single-piece Hall IC with a custom magnetic circuit optimized to switch in response to magnetic signals generated by ferromagnetic targets. The IC contains an advanced digital circuit designed to reduce magnet effects and system deviations. The signal processing design allows the device to operate at target zero speed, independent of air gap, and dynamically adaptable to the carCamshaft speed sensingThe specific operating conditions of the app.

The high-resolution peak detection DAC is used to set the device's adaptive switching threshold, ensuring high accuracy even in the event of a target anomaly. Threshold internal hysteresis reduces the adverse effects of magnetic signal anomalies such as magnetic overshoot associated with targets used in a variety of automotive applications. The output result of this device is a digital representation of the ferromagnet target profile. The ATS675 also features a low-bandwidth filter that increases tolerance to noise interference and the signal-to-noise ratio of the IC.

This device is lead-free and features 100% matte tin leadframe plating.
