1. Functional Diagram
2. Description
1
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.

Chopper
The MLX90224LVA-ABA 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.
Chopper
The output structure is an Open-Drain NMOS
transistor with a capability of 25 mA and
protected against short-circuits.
