Description

Frequency signal for speed output and logic level signal for direction output • Temperature-compensated magnetics and ultra-low offset drift • Wide operating voltage range • Miniature, SOT-89B plastic package • Tape and reel Two separate, built-in Hall sensors and associated logic circuitry provide a frequency signal for speed output and a logic level (high or low) signal for direction output, potentially replacing multiple sensors and electronic components. Temperature-compensated magnetics and ultra-low offset drift with temperature provide a stable output over a full temperature range of -40°C to 125°C [-40°F to 257°F]. Wide operating voltage range of 3.4 Vdc to 24 Vdc increases application flexibility. Tested to moisture sensitivity similar to JEDEC J-STD-020B, MSL Level 1, allowing use in environments where humidity may be a problem. Miniature plastic package supplied on tape and reel for automated assembly, allowing potential savings in PC board space and labor cost. Potential applications include anti-pinch electric motor control systems for power window and seats, magnetic encoding for electronic steering systems, motion control systems for pulleys and belts, garage door openers and sliding doors and position and velocity detection in industrial equipment.
