Overview
Das Index Counter Click Board™ ist eine einfache, hochpräzise Hall-Effekt-Schalterlösung mit Richtungserkennung zum Prototyping. Diese Platine enthält TLE4966K, einen integrierten Dual-Hall-Effekt-Sensor von Infineon. Der Sensor wurde speziell für hochpräzise Anwendungen mit rotierendem Polrad entwickelt, da er eine hohe Empfindlichkeit und Stabilität der magnetischen Schaltpunkte bietet. Da dieser Sensor auf zwei Hall-Sonden basiert, die Informationen über die Richtung und Geschwindigkeit des sich bewegenden Rads liefern, ist dieses Produkt eine ausgezeichnete Wahl für Anwendungen wie Indexzählung, Rotationsgeschwindigkeits- und Richtungsanwendungen sowie motorgetriebene Positionssysteme.
Der Index Counter Click Board™ wird von einer mikroSDK-kompatiblen Bibliothek unterstützt, die Funktionen enthält, die die Softwareentwicklung vereinfachen. Dieses Click Board™ wird als vollständig getestetes Produkt geliefert und ist bereit für den Einsatz auf einem System, das mit der mikroBUS™-Buchse ausgestattet ist.

How Does The Index Counter Click Board™ Work?
The Index Counter Click Board™ is based around the TLE4966K, which is a high sensitivity and high stability of the magnetic switching points sensor with reverse battery protection (-18 V). This sensor has many features that make it a perfect solution for small designs such as the Index Counter Click Board™. One of these features is certainly its high level of integration that allows a minimal number of external components.

The TLE4966K provides excellent temperature compensation capability for keeping the output stable under changing temperature. It is designed specifically for highly accurate applications with a speed signal for every magnetic pole pair, as well as direction information. The TLE4966 Hall Sensors feature two integrated and calibrated sensor elements for detecting direction and counting indexes. This feature eliminates the need for a second sensor and cuts engineering and production costs. Using just one sensor also raises system quality and reliability.
The chopped Double Hall Switch comprises two Hall probes, bias generator, compensation circuits, oscillator, and output transistors.
The bias generator provides currents for the Hall probes and the active circuits. Compensation circuits stabilize the temperature behavior and reduce technology variations.
The Active Error Compensation rejects offsets in signal stages and the influence of mechanical stress to the Hall probes caused by molding and soldering processes and other thermal stresses in the package. This chopper technique together with the threshold generator and the comparator ensures high accurate magnetic switching points.
