Product data sheet Rev. 1 — 16 July 2013 8 of 36 NXP Semiconductors KMA221 Programmable angle sensor Table 6 describes the diagnostic behavior and the resulting output voltage depending on the error case. Furthermore the duration and termination condition to enter and leave the diagnostic mode are given, respectively. [1] Status bit stays set in command register until power-on reset. [2] Depending on the diagnostic level setting. 8. Limiting values [1] Overvoltage on analog output and supply within the specified operating voltage range. Minimum VDD to maximum VDD normal operation All analog circuits are active and the measured angle is available at the analog output. All parameters are within the specified limits. Maximum VDD to Vth(ov) functional operation All analog circuits are active and the measured angle is available at the analog output. Not all parameters are within the specified limits. Vth(ov) to 16 V overvoltage The digital core and the oscillator are active but all other circuits are in Power-down mode. The output is set to the lower diagnostic level. Table 6. Diagnostic behavior Diagnostic condition Duration Analog output Termination condition Low voltage 1 s<t < 10 s 4%V DD functional or normal operation Overvoltage 1 s<t < 10 s 4%V DD functional or normal operation Checksum error n/a 4%V DD or 96 %VDD [2] power-on reset[1] Double-bit error n/a 4%V DD or 96 %VDD [2] power-on reset[1] Magnet-loss 0.5 ms < t < 6 ms 4%V DD or 96 %VDD [2] magnet present[1] Power-loss 2ms 4%V DD or 96 %VDD [2] power-on reset Broken bond wire 0.2 ms < t < 1 ms 4%V DD or 96 %VDD [2] power-on reset[1] Table 5.
