ATS601LSGTN-HT-WM1-T

• Product introduction

The ATS601LSG is Allegro™Camshaft sensorUnique addition to the IC family. This single-element defined power-on sensor IC provides first-falling side detection, high operating mode edge accuracy, and is direction-independent over the entire operating air gap, speed, and temperature range. The ATS601LSG includes an optimized Hall IC and a simple bead configuration.

The unitHall ICand bead configurations can be switched according to the magnetic signal generated by the ferromagnetic target. The IC also has a low-bandwidth filter that improves immunity and the signal-to-noise ratio of the sensor IC. Sophisticated digital circuit design eliminates target geometry discontinuities, magnet and system deviations, and thermal gradients. Signal processing provides true zero-speed performance independent of air gap and dynamically adapts to device performance for operating conditions common in automotive applications, especially cam sensing applications. The output of this device is a digital representation of the target profile of the ferromagnet.

Multiple factory programmable options ensure optimized performance to meet specific application requirements.

The ATS601 is available in a Pb-free 4-pin single SIP package (suffix: SG) with 100% matte tin leadframe plating.
