This device is based on a Dual Mold Package (DMP-4) construction, which integrates a Triaxis position sensing die together with the decoupling capacitors necessary to meet the strenuous ESD and EMC requirements. No PCB is needed. The Triaxis position sensing die is nothing but the one used for the MLX90365 in conventional surface-mount packages (SOIC-8 and TSSOP-16). Similarly to other Triaxis products, the MLX90364 is sensitive to the flux density applied orthogonally and parallel to the IC surface i.e. the 3 components of the flux density applied to the IC (i.e. BX, BY and BZ). This allows the MLX90364 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). MLX90364 reports a programmable ratiometric analog output signal compatible with any resistive potentiometer or programmable linear Hall sensor. Through programming, the MLX90364 provides also a digital PWM (Pulse Width Modulation) output characteristic.

To reach 10mA, the power saving option should be enabled. This option switches off and on internal blocks dynamically. It can be disabled in case of extreme emission requirements or if an analog output is required with a resistor on either supply or output line. 3 This current is due to the charge of output capacitors in PWM push-pull mode. 4 The specified value is valid during early start-up time only; the current might dynamically exceed the specified value, shortly, during the Start-up phase. 5 The minimum specified value is mandatory to reach passive diagnostic output levels.

This is only valid if k = 1. 12 For instance, in case of a rotary position sensor application, Thermal Drift of Sensitivity Mismatch equal ± 0.5% yields to max. ± 0.15 Deg. angular error for the computed angular information (output of the DSP). See “MLX90364 Front-End Application Note” for more details. 13 The Intrinsic Linearity Error refers to the IC itself (offset, sensitivity mismatch, orthogonality) taking into account an ideal rotating field for BX and BY. Once associated to a practical magnetic construction and the associated mechanical and magnetic tolerances, the output linearity error increases. However, it can be improved with the multi-point end-user calibration. The intrinsic Linearity Error for Magnetic angle ∠XZ and ∠YZ can be reduced through the programming of the k factor.

Above 70 mT, the IMC® starts saturating yielding to an increase of the linearity error. 19 Below 20 mT, the performances slightly degrade due to a reduction of the signal-to-noise ratio, signal-to-offset ratio. 20 This is the magnetic gain linked to the Integrated Magneto Concentrator structure. This is the overall variation. Within one lot, the part to part variation is typically ± 10% versus the average value of the IMC gain of that lot. 18 REVISION 007 – OCT 2018 390109036401 Page 20 of 45 MLX90364 Triaxis® Position Sensor Datasheet 11.

Analog Output Mode The Analog Output Mode is a rail-to-rail and ratiometric output with a push-pull output stage configuration allows the use of a pull-up or pull-down resistor. 13.1.3. PWM Output Mode If PWM output mode is selected, the output signal is a digital signal with Pulse Width Modulation (PWM). The PWM polarity is selected by the PWMPOL parameter:  PWMPOL = 1 for a low level at 100%  PWMPOL = 0 for a high level at 100% The PWM frequency is selected by the PWMT parameter. The following table provides typical code for different target PWM frequency and for both low and high speed modes. PWM F (Hz) PWMT (LSB) @13.3MHz PWM res. (μs) PWM res. (%) PWM res.

Enable scaling Parameter (only for LNR type 4 pts) This parameter enables to scale LNR_x_Y from -50% - 150% according to the following formula (Scaled Out)%VDD = 2 x Out%VDD – 50% 13.2.2. CLOCKWISE Parameter The CLOCKWISE parameter defines the magnet rotation direction. • CCW is the defined by the 1-2-3-4 pin order direction for the Dual Mold Package. • CW is defined by the reverse direction: 4-3-2-1 pin order direction for the Dual Mold Package. Refer to the drawing in the sensitive spot positioning sections (Section 18.1.6). 13.2.3. Discontinuity Point (or Zero Degree Point) The Discontinuity Point defines the 0 Deg. point on the circle. The discontinuity point places the origin at any location of the trigonometric circle. The DP is used as reference for all the angular measurements. 360° 0° The placement of the discontinuity point (0 point) is programmable. Figure 4 - Discontinuity Point Positioning 13.2.4. 4-Pts LNR Parameters The LNR parameters, together with the clamping values, fully define the relation (the transfer function) between the digital angle and the output signal. The shape of the MLX90364 transfer function from the digital angle value to the output voltage is described by the drawing below. Six segments can be programmed but the clamping levels are necessarily flat. Two, three, or even six calibration points are then available, reducing the overall non-linearity of the IC by almost an order of magnitude each time. Three to six calibration points will be preferred by customers looking for excellent non-linearity figures. Two-point calibrations will be preferred by customers looking for a cheaper calibration set-up and shorter calibration time.

All the Y-coordinates can be programmed from -50% up to +150% to allow clamping in the middle of one segment (like on the Figure 6), but the output value is limited to CLAMPLOW and CLAMPHIGH values. Between two consecutive points, the output characteristic is interpolated.

Outside of the selected range, the output will remain in clamping levels. 13.2.6. CLAMPING Parameters The clamping levels are two independent values to limit the output voltage range. The CLAMPLOW parameter adjusts the minimum output voltage level. The CLAMPHIGH parameter sets the maximum output voltage level. Both parameters have 16 bits of adjustment and are available for both LNR modes. In analog mode, the resolution will be limited by the D/A converter (12 bits) to 0.024%VDD. In PWM mode, the resolution will be 0.024%DC. 13.2.7. Thermal Output Offset correction (AxE version only) On the version AxE, the two parameters ANGLEOFSSLOPEHOT and ANGLEOFSSLOPECOLD, defined in the section 12, enable to add, to the output an offset depending on the measured temperature depicted in the Figure 7.

The span of this offset is +5.63/-3.37% of the full output scale.
