3422 Datasheet (Allegro MicroSystems) - DIRECTION-DETECTION SENSORS

3422, DIRECTION-DETECTION SENSORS

The integrated circuit contains an internal voltage regulator that powers the Hall sensors and both the analog and digital circuitry.

This regulator allows operation over a wide supply voltage range and provides some immunity to supply noise.

The device also contains CMOS logic circuitry that decode

3422 PRELIMINARY INFORMATION (subject to change without notice) Februaryt 21, 2003 HALL-EFFECT, DIRECTION-DETECTION SENSORS The A3422xKA Hall-effect, direction-detection sensor is a new generation of special-function integrated sensors that is capable of 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 e
