mlx90364 triaxis? position sensor assembly mlx90364 page 4 of 36 datasheet rev 4.1 19/11/2015 2. description the mlx90364 triaxis? position sensor assembly is a high accuracy linear and angular position sensor w hich eliminates need for inclusion of a printed circuit board (pcb) within sensing modules. this device is based on a dual mold package (dmp) c onstruction, which integrates a triaxis position se nsing die together with the decoupling capacitors necessary t o meet the strenuous esd and emc requirements. no p cb is needed. the triaxis position sensing die is nothing but the one used for the mlx90365 in conventional surface- mount packages (soic-8 ? single die & tssop-16 ? dual die ). the decoupling capacitors are x8r type and well su ited for package integration and the target operating temperature range. similarly to other triaxis products, the mlx90364 i s sensitive to the flux density applied orthogonall y 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 movi ng magnet (e.g. rotary position from 0 to 360 degrees or line ar displacement, stroke). mlx90364 reports a programmable ratiometric analog output signal compatible with any resistive potenti ometer or programmable linear hall sensor. through programmin g, the mlx90364 provides also a digital pwm (pulse width modulation) output characteristic. mlx90364 triaxis? position sensor assembly enables the realization of position sensor modules for whic h a pcb is no longer needed: this yield to an increase of t he electrical, mechanical and environmental robustn ess of the final application. figure 2 nopcb ? mlx90364 makes conventional pcb r edundant

mlx90364 triaxis? position sensor assembly mlx90364 page 9 of 36 datasheet rev 4.1 19/11/2015 once the position (angular or linear stroke) inform ation is computed, it is further conditioned (mappe d) vs. the target transfer characteristic and it is provid ed at the output(s) as either a ratiometric analog output level through a 12 bit dac followed by a buffer or a digital pwm output. for instance, the analog output can be programmed f or offset, gain and clamping to meet any rotary position sensor output transfer characteristic: vout( ) = clamplo for min vout( ) = voffset + gain for min max vout( ) = clamphi for max where voffset, gain, clamplo and clamphi are the ma in adjustable parameters for the end-user. the linear part of the transfer curve can be adjust ed through a multi-point calibration: this back-end step consists into either ? up to 4 arbitrary points (5 segments + clamping le vels) calibration or ? a piece-wise-linear (pwl) output transfer characte ristics - 17 equidistant points w/ programmable origin over 16 different angle ranges from 65 to 360 degrees. the calibration parameters are stored in eeprom fea turing a hamming error correction coding (ecc). the programming steps do not require any dedicated pins. the operation is done using the supply and output nodes of the ic. the programming of the mlx9 0364 is handled at both engineering lab and production line levels by the melexis programming u nit ptc-04 with the dedicated mlx90316 daughterboard and mlx90365 software tools (dll ? user interface).

(ii) k when the mapping (b1=x, b2=y) is not selected, k defines the sensitivity mismatch factor that is applied on b1or b2 (according to parameter sel_k ? see belo w). if the mapping (b1=x, b2=y) is selected, this parameter is unused. this parameter is optimized for mapxyz=01 (b1=z, b2 =x) by factory trimming. if another mapping value is selected, melexis recommends to fine tune k in o rder to reach a smaller linearity error (le, see se ction 10). (iii) sel_k when the mapping (b1=x, b2=y) is not selected, sel_k defines the component on which the sensitivity mismatch factor k (see above): sel_k = 0 means b1 k ? b1 and sel_k = 1 means b2 k ? b2. 15.5.3. gainmin and gainmax parameters gainmin and gainmax parameters define the boundarie s of the virtual gain code. outside of these thresholds, the ?gain out of spec? fault is set. if gainsaturation parameter is set, the virtual gai n code is saturated at gainmin and gainmax, and no diagnostic fault is set since the saturations ap plies before diagnostic check. 15.6. filter parameter value filter 0 2 fhyst 0 255 the mlx90364 includes 2 types of filters: ? hysteresis filter: programmable by the fhyst parameter ? low pass fir filters controlled with the filter parameter 15.6.1. hysteresis filter the fhyst parameter is a hysteresis filter. the out put value of the ic is not updated when the digital step is smaller than the programmed fhyst parameter valu e. the output value is modified when the
