GENERAL DESCRIPTION

The  MLX91208is  a  monolithic  sensor  IC  featuring  the  TriaisHall  technology.  Conventional  planar  Hall technology  is  only  sensitive  to  the  flux  density  applied  orthogonally to the IC surface. The IMC-Hallcurrent sensor is sensitive to the flux density applied parallel to the IC surface. This is obtained through an Integrated Magneto-Concentrator which is deposited on the  CMOS  die  (as  an  additional  back-end  step). The IMC-Halltechnology is automotive qualified.

The product is a single chip Hall sensor which provides an output signal proportional to the flux density applied horizontally and is therefore suitablefor current measurement. It is ideally suited as an open loop current sensor for PCB or bus bar mounting. It features small size application design and a simple construction for various current ranges from few Amperes  up to 1000 Amperes.

The transfer characteristic of the MLX91208 is programmable in terms of offset, gainortemperature compensation. The linear analog output is designedfor applicationswhere a very fast responseis required, such as inverter applications.Figure 2: Typical application of MLX91208(magnetic field generated by the current).
