ATS605LSG : Dual Output Differential Speed and Direction Sensor IC

The ATS605LSG provides a single IC solution to rotational position sensing applications with a ferrous gear target. The SG package incorporates a rare earth pellet for ease of manufacturing, consistent performance over temperature, and enhanced reliability.
Three Hall elements are incorporated to create two independent differential channels. These channels are processed by the IC which contains a sophisticated digital circuit designed to eliminate the detrimental effects of magnet and system offsets. Hall differential signals are used to produce a highly accurate speed output and, if desired, provide information on the direction of rotation.
Advanced calibration techniques are used to optimize signal offset and amplitude. This calibration, combined with the digital tracking of the signal, results in accurate switch-points over air gap, speed, and temperature. The open-drain outputs provide voltage output signals which mirror the sensed target’s shape, with a phase separation between the two channels proportionate to the size of the target teeth vs. the Hall element spacing. This sensor IC system is optimized for a variety of applications requiring dual phase gear speed and position signal information or simultaneous high-resolution gear speed and direction information.
The ATS605 is offered in a lead (Pb) free 4-pin SIP package with an integrated back-basing magnet with a 100% matte tin plated leadframe.
