Description
The MLX90374 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 a dual
output stage driver.
The MLX90374 is sensitive to the three
components of the magnetic flux density applied to
the IC (i.e. Bx, By and Bz). This allows the MLX90374
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 MLX90374 provides either a dual PWM output
or a combination of SENT plus a programmable
switch function. In dual PWM output mode, the
circuit offers a wide panel of configurations from
fully redundant signals to individually configurable
outputs, including the choice between several
error reporting modes. In SENT mode, the circuit
delivers enhanced serial messages consisting of
error codes, and user-defined values.
Application Examples
Absolute Rotary Position Sensor
Pedal Position Sensor
Throttle Position Sensor
Ride Height Position Sensor
Absolute Linear Position Sensor
Steering Wheel Position Sensor
Float-Level Sensor
Non-Contacting Potentiometer
