Programmable angle sensor

The KMA200 is an angle sensor system. The MagnetoResistive (MR) element and the mixed signal Integrated Circuit (IC) are integrated 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 angle, zero point, clamping level and a 32-bit identifier. The data is stored permanently in an Electrically Erasable Programmable Read-Only Memory (EEPROM).

The device can be programmed to work either in analog or digital (SPI) output mode. Furthermore, different analog output characteristics are possible. The 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.
