The MLX90224 series is a dual Hall effect latch with dual outputs, operating voltage range of 4.5V to 28V, and features such as phase/direction detection.
The MLX90224 series are dual Hall‑effect latches that detect magnetic flux using switched silicon Hall plates. Versions A and B output two digital signals (speed and phase‑shifted speed) while version B adds direction detection; version C offers the same functions with higher magnetic thresholds.
The device operates from –40 °C to 150 °C, supports a supply voltage of 4.5 V to 28 V, and delivers up to 20 mA output current. Typical specifications include a 200 kHz oscillator for A/B (400 kHz for C), a 15 µs refresh time for A/B, and a power dissipation limit of 300 mW. Mechanical dimensions, pinout, and recommended protection circuitry are also provided.
