Description
The MLX90372 is a monolithic magnetic position
processor IC. It consists of a Triaxis® Hall magnetic
front end, an analog to digital signal conditioner, a
DSP for advanced signal processing and an output
stage driver.
The MLX90372 is sensitive to the three
components of the magnetic flux density applied
to the IC (i.e. Bx, By and Bz). This allows the
MLX90372 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, see fig. 2). It
enables the design of non-contacting position
sensors that are frequently required for both
automotive and industrial applications.
The MLX90372 provides SENT frames encoded
according to a Secure Sensor format. The circuit
delivers enhanced serial messages providing error
codes, and user-defined values. Through
programming, the MLX90372 can also be
configured to output a PWM (Pulse Width
Modulated) signal.
