Intelligent Drivers and Actuators Sensor Interface Since the introduction of the first programmable linear Hall sensor in 1995, Melexis has continuously grown its linear Hall sensor portfolio. The last generation products are MLX90251 and the MLX90277. The MLX90251 is an automotive programmable linear Hall sensor featuring EEPROM. The analog output is proportional to the applied flux density and the transfer characteristic can be adjusted to any specific requirement. The MLX90251 is fully protected and includes several diagnostic modes. The MLX90277 is nothing but 2 isolated dies of the MLX90251 in a single surface-mount package. The MLX90277 allows an elegant and cost-effective implementation of the automotive redundancy requirements.
