The MLX90224 series are dual Hall effect latches. It

includes two Hall effect latch functions of which typi-

cal thresholds are +/- 2.0 mT. In each latch, the mag-

netic flux detection is performed by a switched silicon

Hall plate. The BOP and BRP are temperature-compen-

sated 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 pack-

age. Similarly, the output will be “latched off” (BRP) in

the presence of a North field. Spacing on the plates is

1.85mm.

The MLX90224 B series are designed for direction

detection with a high speed chopper which provides

15µs delay.

Note: Static sensitive device, please observe ESD precautions.
