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.

Modulator

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

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.
