nse-5310 miniature position encoder with zero reference and i2c output www.ams.com revision 1.5 1 - 22 1 general description the tracker nse-5310 is an incremental position sensor with on- chip encoding for direct digital output. a hall element array on the chip is used to derive the incremental position of an external magnetic strip placed above the ic at a distance of 0.3 mm (typ). this sensor array detects the ends of the magnetic strip to provide a zero reference point. the integration of hall-effect position sensors, analog front end and digital signal processing on a single ic chip provides an ingeniously small position sensor, without the need for external pulse counters. direct digital output is accessible over the serial interface using i2c protocol. the tracker nse-5310 provides absolute position information over the length of a magnet pole pair (2 mm). a user can count pole pairs and achieve absolute position information over the entire length of the magnet (essentially unlimited). with better than 0.5 micron resolution, the tracker is a robust, cost-effective alternative to miniature optical encoders. it can be used as a linear or off-axis rotary encoder. figure 1. tracker nse-5310 block diagram 2 key features ?? direct digital output using i2c protocol ?? end-of-magnet detection for built-in zero reference ?? 0.488 m resolution ?? < 2 m bi-directional repeatability ?? < 10 m absolute error ?? on-chip temperature sensor ?? magnetic field strength monitor ?? available in tssop-20 ?? custom packaging such as wafer-level chip scale packaging can be provided. minimum order quantities may apply. ?? rohs compliant 3 applications the nse-5310 is ideal for micro-actuator and servo drive feedback, replacement for optical encoders, optical and imaging systems, consumer electronics, precision biomedical devices, instrumentation and automation, automotive applications, and integrated closed-loop motion systems using new scale?s squiggle micro motor. magincn magdecn ao pwm scl prog csn vdd5v vdd3v3 nse-5310 ldo 3.3v incremental interface pwm interface programming parameters sin cos agc pos agc mag sda linear hall array & frontend amplifier agc dsp absolute interface (i 2 c) temperature sensor otp register

www.ams.com revision 1.5 12 - 22 nse-5310 datasheet - application information 8.2 automatic gain control (agc) as the magnetic input field varies non-linearly with the air gap between sensor and magnet, the gain is controlled to an optimu m input signal for the sd adc. the magnitude output is compared to a target register value. the most significant eight bits are used. if the actua l magnitude differs from the target value, an up/down signal for the agc counter signal is generated. for air gap detection functionality, two magnitude-change outputs are derived from the agc counter up/down signals while the lo op is controlling the amplitude back to the target amplitude. magnitude increasing (magincn) and magnitude decreasing (magdecn) signa ls indicate air gap (sin/cos amplitude) changes. both signals are high for saturation of the agc counter (running into upper / lower limit) and produce a non-valid-range alarm. the output pins can be connected together in wired-or configuration to produce a single nvrn bit. for fa ster power-up and response time, a successive approximation algorithm is implemented. 8.3 temperature sensor the temperature sensor provides the junction temperature information over the serial interface. 8.4 i2c user interface the device is accessible via an i2c two-wire serial interface. the default address is a<6:0>1000000. a<5:1> can be defined by t he otp i2c address. a0 can be selected by pulling up pin 11 (default internal pull down). csn (default internal pull up) must be low durin g i2c data transmission. figure 9. i2c read out by an c-master in addition to the position data, magnitude and temperature sensor information can be read out as described in automatic gain control (agc) on page 12 and temperature sensor on page 12 . table 10. temperature sensor characteristics parameter conditions min typ max units absolute error trimmed see i2c user interface on page 12 10 oc conversion rate for continuous readout (1303 clock cycles between conversion) 767 sample/s temperature range specified temperature range -30 70 oc readout range design limit for temperature range -50 80 oc resolution temp [oc] = output code [lsb] x 0.667 [oc/lsb] - 75[oc] 8bit 0.667 oc/lsb clock frequency system clock (4 mhz) divided by 4 1 mhz d11 - d0: linear position offset compensation finished: ?high? indicates a data valid. cordic overflow: ?high? indicates a dsp calculation overflow. linearity alarm: ?high? indicates the adc i nput range exceeds 625mv (=filter overflow) magincr / magdecr ?high? or connection indicates changi ng magnitude and non-valid input range (see also pin 2 and 3) ack address by slave 9 mag incr decr scl sda 1 91 91 1 s ack master ack master data byte 1 data byte 3 data byte 2 lin alarm cordic over flow offset comp finish d0 d1 d2 d3 d4 d5 d6 d7 d8 d9 d10 d11 r/ a0p a1 a2 a3 a4 a5 1 type identifier address read agc7

www.ams.com revision 1.5 15 - 22 nse-5310 datasheet - application information figure 12. pwm output signal 8.7 magnetic strip requirements the nse-5310 requires a magnetic strip with alternate poles (north-s outh) of pole length of 1 mm and pole pair length of 2 mm. a half pole is required at each end of the strip. the length of the strip determines the maximum measured stroke; it must be 3 mm greater than the stroke in 1 mm increments (1.5 mm on each end). a circular magnet may be used to achieve off-axis rotary encoding. 8.7.1 mounting the magnet vertical distance: as a rule of thumb, the gap between chip and magnet should be ? of the pole length, that is z=0.5mm for the 1.0mm pole length of the magnets. however, the gap also depends on the strength of the magnet. the nse-5310 automatically adjusts for fluc tuating magnet strength by using an automatic gain control (agc). the vertical distance should be set such that the nse-5310 is in the ?green? range. see z-axis range indication (?red/yellow/green? indicator) on page 14 for more details. alignment of multi-pole magnet and ic: when aligning the magnet strip or ring to the nse-5310, the centerline of the magnet strip should be placed exactly over the hall array. a lateral displacement in y-direction (across the width of the magnet) is acceptable as long as it is within the active area of the magnet. the active area in width is the area in which the magnetic field strength across the width of th e magnet is constant with reference to the centerline of the magnet. table 13. magnetic strip requirements parameter value note pole length 1 mm pole pair length 2 mm 1.2% accuracy of magnetic pole length determines accuracy of linear measurement magnetic strip length stroke + 3 mm the magnet strip must be in 1 mm increments. a ? pole is required at each end. magnetic strip area 1 mm x 2 mm size recommended for tssop package magnetic field temp drift -0.2%/k max recommended - for example samarium cobalt recoma28 is - 0.035%/k 4098s 4097s 1/f pwm pw max pw min 1999.5 m (pos 4095) 0 m (pos 0) position 1s
www.ams.com revision 1.5 16 - 22 nse-5310 datasheet - application information lateral stroke of multi-pole strip magnets: the lateral movement range (stroke) is limited by the area at which all hall sensors of the ic are covered by the magnet in either direction. the hall array on the nse-5310 has a length of 2.0mm, hence the total stroke is: maximum lateral stroke = length of active area ? length of hall array (eq 2) note: active area in length is defined as the area containing poles with the specified 1.0mm pole length. shorter poles at either edg e of the magnet must be excluded from the active area. figure 13. magnetic strip alignment note: further examples including use in off-axis rotary applications are shown in the ?magnet selection guide?, available for downloa d at www.ams.com/eng/content/view/download/11922 figure 14. vertical cross section 0.22990.100 0.23410.100 0.77010.150 package outline 3.04750.235 3.2000.235 die c/l 2.5760.235
