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.
