1. product profile 1.1 general description the kma200 is an angle sensor system. the magnetoresistive (mr) element and the mixed signal integrated circuit (ic) are integr ated in one package. this angle system is already pre-programmed, offsets are compensated and therefore, ready to use. via the serial peripheral interface (spi) the kma200 is user programmable. this allows user specific adjustments of the maximum an gle, zero point, clamping level and a 32-bit identifier. the data is stored permanently in an electrically erasable programmable read-only memo ry (eeprom). the device can be programmed to work either in analog or digital (spi) output mode. furthermore, different analog output characteri stics are possible. th e resolution is better than 0.05 ? . the implemented online diagnosis supervises the input and output signals as well as the data processing. deviations and failures of the angle value are indicated in the output signal. overall temperature supervision is implemented. 1.2 features and benefits kma200 programmable angle sensor rev. 8 ? 7 december 2011 product data sheet ? magnetic field angular sensing ? one package angle sensor system ? high accuracy ? resolution better than 0.05 ? ? operating temperature range from ? 40 ? c to +160 ? c ? digital or analog output signals (user programmable) ? online diagnosis ? overvoltage protection at all external pins ? bidirectional digita l interface (spi) ? eeprom (user programmable) ? programmable maximum angle up to 180 ? ? programmable zero point ? pre-calibrated, ready to use device

[1] reactivation for angular measurement with valid angle information (normal operation mode) only by new external power-on reset temperature supervision the chip temperature measured within the kma200 can be used to detect over-temperature conditions. two temperature levels are defined: the temperature warning level and the temperature shutdown level. the user can evaluate the temperature warning if digital output mode is selected. when the device temperature exceeds the warning level, the error flag in the digital output word is set. the other data bits st ill show the angle info rmation. in the analog output modes, the device temperature warning is not available. if the temperature exceeds the over-temperature shutdown level, the kma200 switches off. table 4. summary kma200 behavior at diagno sis conditions in normal operation mode error appearance analog output digital output oscillator fail detection [1] high-impedance state [1] high-impedance state cyclic redundancy check (crc) [1] high-impedance state [1] diagnosis bit set watchdog [1] high-impedance state [1] high-impedance state input stage (including magnet lost) hi gh-impedance state diagnosis bit set output stage [1] high-impedance state - over-temperature warn ing - diagnosis bit set over-temperature shutdown [1] high-impedance state [1] high-impedance state overvoltage high-impedance state high-impedance state reverse polarity high-impedance state high-impedance state
