Description:
Hall-effect/ direction-detection sensors.
3421, HALL-EFFECT/ 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
3421 AND 3422 PRELIMINARY INFORMATION (subject to change without notice) September 6, 2000 HALL-EFFECT, DIRECTION-DETECTION SENSORS The A3421xKA and A3422xKA Hall-effect, direction-detection sensors are a new generation of special-function integrated sensors that are capable of sensing the direction of rotation of a ring magnet.
These transducers provide separate digital outputs that provide information on magnet rotation speed, direction, and magnet pole count.
These devices eliminate the maj
