7. Diagnostic features
The KMA210 provides several diagnostic features:
7.1 CRC and EDC supervision
The KMA210 includes a supervision of the programmed data. At power-on, a CRC of the
non-volatile memory is performed. Furthermore the memory is protected against bit
errors. Every 16-bit data word is saved internally as a 22-bit word for this purpose. The
protection logic corrects any single-bit error in a data word, while the sensor continues in
normal operation mode. Double-bit errors per word will be detected and switches the
device into diagnostic mode.
7.2 Magnet-loss detection
If the applied magnetic field strength is not sufficient, the KMA210 can raise a diagnostic
condition. In order to enter the diagnostic mode, due to magnet-loss, the detection has to
be enabled first. The device can be programmed into active diagnostic mode, where the
output is driven below 4 %V
DD
or above 96 %V
DD
.
7.3 Power-loss detection
The power-loss detection circuit enables the detection of an interrupted supply or ground
line of the mixed signal IC in normal operation mode up to the maximum operating supply
voltage. In the case of a power-loss condition, two internal switches in the sensor are
closed, connecting the pin of the analog output to the supply voltage and the ground pins.
