ARS19510LUB: Two-Wire, Differential, Vibration-Resistant Sensor IC with Speed and Direction Output

Description

The ARS19510LUB integrates an advanced Hall-effect circuit IC and EMC protection components in a single overmolded package. The optimized, user-friendly solution provides direction detection and true zero-speed digital gear tooth sensing for challenging environments, such as automotive and industrial transmissions and a wide variety of gear-tooth sensing applications.

The IC’s patented advanced algorithms provide EMI compliance to the harshest automotive requirements, capability to withstand full range sudden and dynamic air gap shifts, and vibration suppression.

The speed and direction of the target are communicated through a variable pulse-width output protocol. The ARS19510 is particularly adept at handling vibration without sacrificing maximum air gap capability or creating any erroneous “direction” pulses. The advanced vibration detection algorithm will systematically calibrate the sensor IC on the initial teeth of true target rotation and not on vibration, ensuring an accurate running mode signal. Advanced packaging combined with innovative algorithms make the ARS19510 an ideal solution for a wide range of speed and direction-sensing needs.

This device is available in a lead (Pb) free 2-pin SIP package with tin-plated leadframe.
