Melexis MLX90371 Triaxis Position Processors
Melexis MLX90371 Triaxis Position Processors are monolithic sensors sensitive to the three components of the flux density applied to the IC (i.e., BX, BY, and BZ). This allows the MLX90371 with the correct magnetic circuit to decode the absolute position of any magnet moving in its vicinity (e.g., a rotary position from 0° to 360° or linear displacement). This processor reports a programmable ratiometric analog output signal compatible with any resistive potentiometer or programmable linear Hall sensor. The MLX90371 devices can provide a digital PWM (Pulse Width Modulation) output characteristic through programming.
