The MLX90224 series are dual Hall-effect latch ICs. It includes two Hall-effect latch functions of which typical thresholds are ± 2.0mT.

The magnetic flux detection is performed through a fast circuitry featuring a continuous offset cancellation technique (quadrature-spinning current and chopper-stabilized amplifier).

The spacing of the plates is 1.85 mm. The BOP and BRP are temperature-compensated (+500 ppm/Deg.C.). The output refresh rate is 15 us.

The MLX90224-A quadrature outputs are latched on in the presence of a sufficiently strong South pole magnetic flux density (BOP) facing the marked side of the package. Similarly, the output are latched off in the presence of a sufficiently strong North magnetic flux density (BRP).

The MLX90224-B provides a double-speed and direction outputs derived from both individual quadrature signals.
