preliminary may 07 2. description the mlx90333 is a monolithic sensor ic featuring the tria ? is ? hall technology. conventional planar hall technology is only sensitive to the flux densit y applied orthogonally to the ic surface. the tria ? is ? hall sensor is also sensitive to the flux density applied pa rallel to the ic surface. this is obtained through an integrated magneto-concentrator (imc ? ) which is deposited on the cmos die (as an additional back-end step). the mlx90333 is sensitive to the 3 component s of the flux density applied to the ic (b x , b y and b z ). this allows the mlx90333 to sense any magnet moving in its surrounding and it enables the design of novel generation of non-contacting joystick position sensors which are often required for both automotive and industrial applications (e.g. man-machine interface). furthermore, the capability of measuring b x , b y and b z allows the mlx90333 to be considered as universal non-contacting position sensor i.e. not lim ited to joystick applications. for instance, a linear travel can be sensed with the mlx90333 once included in a specific magnetic design. in combination with the appropriate signal processing , the magnetic flux density of a small magnet (axial magnetization) moving above the ic can be measured in a non-contacting way (figure 3). the two (2) angular information are computed from the three (3 ) vector components of the flux density (i.e. b x , b y and b z ). mlx90333 reports two (2) linear output signals. the output formats are selectable between analog, pwm and serial protocol. figure

maximum-rated conditions for extended periods may affect device reliability. 6. detailed description as described on the block diagram (figure 1 and figure 2), the magnetic flux density applied to the ic is sensed through the tria ? is ? sensor front-end. this front-end consis ts into two orthogonal pairs (for each of the two directions parallel with the ic surface i. e. x and y) of conventional planar hall plates (sensitive element ? blue area on figure 4) and an integrated magneto-concentrator (imc ? yellow disk on figure 4). bz bz bz bz figure 4 - tria ? is ? sensor front-end (4 hall plates + imc ? disk) two orthogonal components (respectively b x and b y ) proportional to the parallel components (respectively b x// and b y// ) are induced through the imc and can be measured by both respective pairs of conventional planar hall plates as those are sensitive to the flux density applied orthogonally to them and the ic surface. the third component b z is also sensed by those four (4) conventional hall plates as shown above. mlx90333 triaxis 3d-joystick position sensor 3901090333 page 8 of 38 data sheet rev. preliminary may 07 in summary, along x-axis, the left hall plate measures ?b x - b z ? while the right hall plate measures ?-b x - b z ?. similarly, along the y-axis, the left hall plate measures ?b y - b z ? while the right hall plate measures ?-b y - b z ?. through an appropriate signal processing, the tria ? is ? sensor front-end reports the three (3) components of the applied magnetic flux density b i.e. b x , b y and b z . indeed, by subtracting the signal s from the two (2) hall plates in each pair, the components b x and b y are measured while b z is cancelled. to the contrary, by adding th e signals from the two (2) hall plates in each pair, the component b z is measured while b x and b y are cancelled in a joystick based on a ?gimbal? mechanism as shown on figure 3 (left), the magnet (axial magnetization) moves on a hemisphere centered at the ic. the flux density is described through the following relationships: ) ( ) ( ) ( ) ( ) ( ) ( cos cos b sin cos b cos sin b z y x ? = ? = ? = those components are plotted on the fi gure 5,

three (3) components of the applied flux density are provided to the adc (analog-t o-digital converter ? figure 8 and figure 9). the hall signals are processed through a fully differential analog chain featur ing the classic offset cancellation technique (hall plate quadrature spinning and chopper-stabilized amplifier). the amplitude of v z is smaller than the other two (2) components v x and v y due to fact that the magnetic gain of the imc only affects the components parallel to the ic surface. mlx90333 triaxis 3d-joystick position sensor 3901090333 page 10 of 38 data sheet rev.

adc (configurable ? 14 or 15 bits) and provided to a dsp block for further processing. the dsp stag e is based on a 16 bit risc micro-controller whose primary function is the extraction of the two (2) angular information from the three (3) raw signals (after so- called front-end compensation steps) through the following operations: ? ? ? ? ? ? ? ? = z z x v k v atan ? ? ? ? ? ? ? ? = z z y v k v atan where k z is a programmable parameter. in a joystick based on a ?ball & socket? joint as shown on figure 3 (right), the magnet (axial magnetization) moves on a hemisphere centered at the pivot point. the flux density is described through slightly more complex equations but the mlx90333 o ffers an alternate algorithm to extract both angular informations: ? ? ? ? ? ? ? ? + = 2 2 ) ( ) ( y t z z x v k v k v atan ? ? ? ? ? ? ? ? + = 2 2 ) ( ) ( x t z z y v k v k v atan where k z and k t are programmable parameters. the dsp functionality is governed by the micro-code (firmware ? f/w) of the micro-controller which is stored into the rom (mask programmable). in addition to the atan function, the f/w controls the whole analog chain, the output transfer characteristic, the output protocol, the progr amming/calibration and also the self-diagnostic modes. in the mlx90333, the atan function is computed via a look-up table (i.e. it is not obtained through a cordic algorithm). due to the fact that the atan operation is performed on the ratios v x /v z and v y /v z , the angular information are intrinsically self-compensated vs. flux density variations (due to airgap change, thermal or ageing effects) affecting the magnetic signal. this feat ure allows therefore an improved thermal accuracy vs. joystick based on conventional linear hall sensors. once the angular information is computed (over 360 degrees), it is further conditioned (mapped) vs. the target transfer characteristic and it is provided at the output(s) as: ? an analog output level through a 12 bit dac followed by a buffer ? a digital pwm signal with 12 bit depth (programmable frequency 100 hz 1 khz) ? a digital serial protocol (sp ? 14 bits computed angular information available) mlx90333 triaxis 3d-joystick position sensor 3901090333 page 12 of 38 data sheet rev. preliminary may 07 for instance, the analog output can be programmed fo r 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 vout( ) = clamplo for min vout( ) = voffset + gain for min max vout( ) = clamphi for max where voffset, gain, clamplo and clamphi are t he main adjustable parameters for the end-user. the linear part of the transfer curve can be adjusted th rough a 3 point calibration. once only one output is used, a 5 point calibration is also available for further improvement of the linearity. the calibration parameters are stored in eeprom feat uring a hamming error correction coding (ecc). the programming steps do not requi re any dedicated pins. the operation is done using the supply and output nodes of the ic. the programming of t he mlx90333 is handled at both engineering lab and production line levels by the melexis programming unit ptc-04 with the mlx90316 daughterboard and dedicated software tools (dll ? user interface). mlx90333 triaxis 3d-joystick position sensor

output mode is a rail-to-rail and ratiomet ric output with a push-pull output stage configuration allows the use of a pull-up or pull-down resistor. 14.2.2. pwm output mode if one of the pwm output modes is selected, the out put signal is a digital signal with pulse width modulation (pwm). in mode 5, the output stage is an open drain nmos tran sistor (low side), to be used with a pull-up resistor to v dd . in mode 7, the output stage is a push-pull stage for which melexis recommends the use of a pull-up resistor to v dd . the pwm polarity of the out 1 (out 2) is selected by the pwmpol1 (pwmpol2) parameter: ? pwmpol1 (pwmpol2) = 0 for a low level at 100% ? pwmpol1 (pwmpol2) = 1 for a high level at 100% mlx90333 triaxis 3d-joystick position sensor 3901090333 page 20 of 38 data

digital serial protocol mode. the mlx90333 is considered as a slave node. see the dedicated serial protocol sectio n for a full description (section tbd). 14.3. output transfer characteristic

arctangent of y/z. it is possible to invert the polarity of these angles via the par ameters alpha_pol and beta_pol set to ?1?. the mlx90313 can also be insensitive to the field polarity by setting the alpha_mod180/beta_mod180 to ?1?. mlx90333 triaxis 3d-joystick position sensor 3901090333 page 21 of 38 data sheet rev. preliminary may 07 x y z 14.3.2. alpha/beta discontinuity point (or zero degree point) the discontinuity point defines the ze ro point of the circle (alpha or be ta). the discontinuity point places the origin at any location of the trigonometric circle (see figure 12). for a joystick application, melexis recommends to set the dp to zero. 14.3.3. lnr parameters the lnr parameters, together with the clamping values, fully define the relation (the transfer function) between the digital angles (alpha a nd beta) and the output signals. the shape of the mlx90333 transfer function from t he digital angle values to the output voltages is described by the drawing below (see figure 11). four segments can be programmed but the clamping levels are necessarily flat. alpha alphaout alpha_s1 alpha_s0 360 clamping low clamping high alpha_x alpha_y clamphigh clamplow 0%

14.3.4. clamping parameters the clamping levels are two independent values to limit the output voltage range. the clamp_low parameter adjusts the minimum output voltage leve l. the clamp_high parameter sets the maximum output voltage level. both parameters have 16 bits of adjustment. in analog mode, the resolution will be limited by the d/a conver ter (12 bits) to 0.024%v dd . in pwm mode, the resolution will be 0.024% dc . in spi mode, the resolution is 14bits or 0.022deg over 360deg. 14.3.5. deadzone parameter the dead zone is defined as the angle window between 0 and 359.9999 (see figure 12 ). when the digital angle (alpha or beta) lies in this zone, the ic is in fault mode (resonfault must be set to ?1? ? see 14.7.1). in case of alpha_mod180 (or beta_mod180) is not set, the angle between 180 and 360 will generate a ?deadzone? fault, unless deadzone=0. programmable forbidden zone programmable 0 point 0 180 90 z x figure 12 ? discontinuity point and dead zone (alpha ? idem

frequency for the dsp. ? highspeed = 0 selects the slow mode with a 7 mhz master clock. ? highspeed = 1 selects the fast mo de with a 20 mhz master clock. for better noise performance, the slow mode must be enabled. 14.5.2. gainmin and gainmax parameters the mlx90333 features an automatic gain control (agc ) of the analog chain. the agc loop is based on (v x )2+ (v y )2 + (v z )2 = (amplitude)2 = (radius)2 and it targets an amplitude of 90% of the adc input span. the current gain can be read out with the progra mming unit ptc-04 and gives a rough indication of the applied magnetic flux density (amplitude). gainmin & gainmax define the boundaries within the gain setting is allowed to vary. outside this range, the outputs are set in diagnostic low. 14.5.3. fieldthres_min and fieldthres_max parameters the strength of the applied field is constantly calcul ated in a background process. the value of this field can be read out with the ptc-04 and fieldthres_min & fieldthres_max define the boundaries within the actual field strength (radius) is allowed to vary. outside this range, the outputs are set in diagnostic low. mlx90333 triaxis 3d-joystick position sensor 3901090333 page 24 of

the fhyst parameter ? low pass fir filters controll ed with the filter parameter ? low pass iir filter controlled with the filter parameter and the coefficients filter a1 and filter a2 note: if the parameter fswap is set to ?1?, the filter ing is active on the digital angle. if set to ?0?, the filtering is active on the output transfer function. 14.6.1. hysteresis filter the fhyst parameter is a hysteresis filter. the output value of the ic is not updated when the digital step is smaller than the programmed fhyst parameter value. the output value is modified when the increment is bigger than the hysteresis. the hysteresis filter reduces therefore the resolution to a level compatible with the internal noise of the ic. the hy steresis must be programmed to a value close to the noise level. please note that for the programmable version, the fh yst parameter is set to 4 by default. if you do not wish this feature, please set it to ?0?. 14.6.2. fir filters the mlx90333 features 6 fir
