2 General description
The new IMC-Hall® current sensor MLX91205 is a
single axis integrated magnetic sensor based on
the Hall Effect. It produces an analog linear, ratio-
metric output voltage proportional to the applied
magnetic field parallel with the chip surface.
The circuit is fabricated using a standard CMOS
process. The additional ferromagnetic layer
(IMC-Hall® = Integrated Magnetic Concentrator,
Triaxis® Technology) that is added in a simple
post-processing step, amplifies the magnetic field
and concentrates it on the Hall elements.
Therefore, the circuit features very high magnetic
sensitivity, low offset, and low noise.
The MLX91205 is ideally suited for current
sensing in automotive and industrial
environments.
There are 2 different product versions available.
The 91205HB features a linear magnetic field
range of ±25mT and the 91205LB features a linear
range of ±10mT. HB refers to a high magnetic
field, whereas LB refers to a low magnetic field
range.
