A3422LKA Descrizione generale

Digital Switch Bipolar Switch Open Collector Hall Effect 5-SIP

Caratteristiche principali

The A3422xKA Hall-effect, direction-detection sensor IC is a new generation of special-function integrated devices that is applicable to sensing the direction of rotation of a ring magnet. This transducer provides separate digital outputs that provide information on magnet rotation speed, direction, and magnet pole count. This device eliminates the major manufacturing hurdles encountered in fine-pitch direction-detection applications, namely maintaining accurate mechanical location between the two active Hall elements. Here, the two Hall elements are photo-lithographically aligned to better than 1 μm, as contrasted with 100 μm or worse mechanical location tolerance when manufactured discretely. This highly sensitive, temperature-stable, magnetic transducer is ideal for use in digital-encoder systems in the harsh environments of automotive or industrial applications. The A3422xKA is a high-sensitivity device optimized for use with high-density magnets.
