Description The MLX90360 is a monolithic sensor IC sensitive to the flux density applied orthogonally and parallel to the IC surface. The MLX90360 is sensitive to the three components of the flux density applied to the IC (i.e. BX, BY and BZ). This allows the MLX90360 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, stroke - Figure 2). It enables the design of novel generation of non-contacting position sensors that are frequently required for both automotive and industrial applications. MLX90360 reports a programmable ratiometric analog output signal compatible with any resistive potentiometer or programmable linear Hall sensor. Through programming, the MLX90360 provides also a digital PWM (Pulse Width Modulation) output characteristic.

Description As described on the block diagram the three vector components of the magnetic flux density (BX, BY and BZ) applied to the IC are sensed through the sensor front-end. The respective Hall signals (VX, VY and VZ) are generated at the Hall plates and amplified. The analog signal processing is based on a fully differential analog chain featuring the classic offset cancellation technique (Hall plate 2-Phases spinning and chopper-stabilized amplifier). The conditioned analog signals are converted through an ADC (15 bits) and provided to a DSP block for further processing. The DSP stage is based on a 16 bit RISC micro-controller whose primary function is the extraction of the position from two (out of three) raw signals (after so-called front-end compensation steps) through the following function: α = ∠(V1 , k ⋅ V2 ) where alfa is the magnetic angle 1 > > ) / ) ) *! , " 4" / Page 9 of 35 Datasheet Dec/13 MLX90360  Triaxis Position Sensor IC '" )% ? + )"# )( "(+ )"# .
