Package

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 B

sated and give a sensitivity temperature coefficient of

500 ppm/

The MLX90224 A, C output transistor will be “latched

on” (B

age. Similarly, the output will be “latched off” (B

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

15 s delay.
