Linear Hall SensorsShort Description
Since the introduction of the first programmable linearHall
sensor in 1995, Melexis has continuously grown itslinear Hall
sensor portfolio. The last generationproducts are MLX90251 and the
MLX90277.The MLX90251 is an automotive programmable linearHall
sensor featuring EEPROM. The analog output isproportional to the
applied flux density and the transfercharacteristic can be adjusted
to any specific
requirement. The MLX90251 is fully protected andincludes several
diagnostic modes.The MLX90277 is nothing but 2 isolated dies of
theMLX90251 in a single surface-mount package. TheMLX90277 allows
an elegant and cost-effectiveimplementation of the automotive
redundancyrequirements.
