Functional Diagram Replaced with Logic for MLX90224 B 2 Chopper 4 Chopper REVISION 009 – JAN 18 3901090224 The MLX90224 is a dual Hall effect latch. 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 MLX90224EVA-AAA 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 of the Hall plates is 1.85 mm. The output structure is an Open-Drain NMOS transistor with a capability of 25 mA and protected against short-circuits. 3 Pin # 1 2 3 4 Packing Form BU (Bulk) 2.

Glossary of Terms Gauss, Tesla: Two units to quantify a magnetic flux density. Conversion: 1 mT = 10 Gauss Bop: B Operating Point: When the magnetic flux density increases and reaches the Bop value, the output switches on. This value is in Gauss. Brp: B Release Point: When the magnetic flux density decreases and reaches the Brp value, the output switches off. This value is in Gauss. 4.
