The MLX90224 series are dual Hall effect latches. It includes two Hall effect latch functions of which typical thresholds are +/- 2.0 mT. In each latch, the magnetic flux detection is performed by a switched silicon Hall plate. The BOP and BRP are temperature-compensated and give a sensitivity temperature coefficient of 500 ppm/oC to compensate popular magnets. The MLX90224 A, C output transistor will be "latched on" (BOP) in the presence of a sufficiently strong South pole magnetic field facing the marked side of the package. Similarly, the output will be "latched off" (BRP) in the presence of a North field. Spacing on the plates is 1.85mm.
