tle5009 product description data sheet 7 rev. 1.1, 2012-04 1 product description 1.1 overview the tle5009 is an angle sensor with analog outputs. it det ects the orientation of a ma gnetic field by measuring sine and cosine angle components with g iant m agneto r esistance ( gmr ) elements. it provides analog sine and cosine output voltages that describe the magnet angle in a range of 0 to 360. the differential gmr bridge signals are temperature comp ensated and independent of the magnetic field strength to maintain constant output voltage over a wide temper ature and field range. the a nalog output is designed for differential applications. the output voltages are designed to use the dynamic ran ge of an a/d-converter using the same supply as the sensor as voltage reference. product type tle5009-e2000 and tle5009-e2010 are intended for use in circuits with 5 volts supply. product types tle5009-e1000 and tle5 009-e1010 are intended for use in 3.3v applications. product types tle5009-e2010 and TLE5009-E1010 have improved angular accuracy achieved by production trimming at two temperatures. 1.2 features ? 3v to 5.5v operating supply voltage ? low current consumption and very quick start up ? overvoltage detection ? 360 contactless angle measurement ? output amplitude optimized for circuits with 3.3v or 5v supply voltage (type -e10x 0 or -e20x0 respectively) ? immune to airgap variations due to gmr based sensing principle ? output amplitude constant over a wide temperature range: -40c to 150c (junction temperature) ? high accuracy typically 0.6 overall angle error ? aec-q100 automotive qualified ? green package with lead-free (pb-free) plating 1.3 target applications the tle5009 gmr angle sensor is designed for angular position sensing in automotive applications. its high accuracy combined with short propagation delay makes it suitable for syst ems with high speeds and high accuracy demands such as rotor position measurement for electric motor commutation. at the sa me time its fast start-up time and low overall power consumption enables the device to be employed in low-power applications. extremely low power consumption can be achieved with power cycling, where the device excells with fastest power on time. ? rotor position sensing for electric motor commutation ? rotary switches ? steering angle sensing ? valve or flap position sensing product type marking ordering code package tle5009-e2000 0092000 sp000912760 pg-dso-8 tle5009-e1000 0091000 sp000912764 pg-dso-8 tle5009-e2010 0092010 sp000912770 pg-dso-8 TLE5009-E1010 0091010 sp000912774 pg-dso-8
tle5009 functional description data sheet 8 rev. 1.1, 2012-04 2 functional description 2.1 general the gmr sensor is implemented using vertical integr ation. this means that the gmr sensitive areas are integrated above the analog portion of the tle500 9 chip. these gmr elements change their resistance depending on the direction of the magnetic field. four individual gmr elements are connected in a wheatstone bridge arrangement. each gmr element senses one of two components of the applied magnetic field: ? x component, v x (cosine) or the ? y component, v y (sine) the advantage of a full-bridge structure is that the amplit ude of the gmr signal is doubled and temperature effects cancel out. figure 1 sensitive bridges of the gmr sensor note: in figure 1 , the arrows in the resistors symbolize the direction of the reference layer. size of the sensitive areas is greatly exagerated for better visualisation. the output signal of each bridge is unambiguous in a range of 180. therefor e two bridges are oriented orthogonally to each other to measure 360. with the trigonometric function arctan, the true 360 angl e value that is represented by the relation of x and y signals can be calculated according to equation (1) .
