Description

The MLX90371 is a monolithic sensor sensitive to

the three components of the flux density applied

to the IC (i.e. B

, B

and B

). This allows the

MLX90371 with the correct magnetic circuit to

decode the absolute position of any magnet

moving in its vicinity (e.g. rotary position from 0

to 360 Degrees or linear displacement, see

Figure 2).

The MLX90371 reports a programmable

ratiometric analog output signal compatible with

any resistive potentiometer or programmable

linear Hall sensor. Through programming, the

MLX90371 can provide a digital PWM (Pulse

Width Modulation) output characteristic.
