Figure 4: Block diagram – BMW I20 CA + NFC, LIN (SP2021)
Operating voltages
- Operating voltage range: +Ubat = 9V to 16V DC
- LIN operating voltage range: +Ubat = 8V to 18V DC
- Test voltage for EOL: +Ubat = 12V ± 2% DC
Current consumption
- Series parts current consumption:
o Quiescent current: I
quies
≤ 400µA for 4 TAGE per vehicle
I
quies
≤ 200µA for 2 TAGE per vehicle
CA = 65µA
CA + NFC = 150µA
o Active current: I
active
≤ 250mA
CA < 10mA
CA + NFC < 120mA
The final values have to be defined with series parts by Huf-HQ.
