Position Sensing Simple Magnetic Design Programmable Measurement Range Programmable Linear Transfer Characteristic
(Multi-points) SENT output (according to SAE J2716-2010) 12 bit Resolution - 10 bit Thermal Accuracy 48 bit ID Number option Single Die – SOIC-8 Package RoHS Compliant Dual Die (Full Redundant) – TSSOP-16 Package
RoHS Compliant Output Thermal Offset correction
The MLX90367 is a monolithic sensor IC sensitive to the flux density applied orthogonally and parallel to the IC surface.
The MLX90367 is sensitive to the three components of the flux density applied to the IC (i.e. BX, BY and BZ). This allows the MLX90367 with the correct magnetic circuit to decode the absolute position of any moving magnet (e.g. rotary position from 0 to 360 Degrees or linear displacement, stroke). It enables the design of novel generation of non-contacting position sensors that are frequently required for both automotive and industrial applications.
MLX90367 provides SENT Frames encoded according the Throttle sensor format or Secure Sensor format. The circuit delivers enhanced serial messages providing error codes, and user-defined values.
