Description
The MLX91208 is 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 (IMC-Hall®) 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 suitable for 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, gain or temperature
compensation. The linear analog output is designed for
applications where a very fast response is required, such as
inverter applications.
