Tool/software:
hi expert,
my customer use TCAN4550-Q1, now they find No message at low temperatures in TCAN4550-Q1, they are not sure if tcan4550-q1 have problem.
their system is NFC--MCU--CAN, NFC use SPI transfer the signal to mcu, and mcu use SPI transfer signal to tcan4550-q1, at last tcan4550-q1 transfer the signal to other ECU. so they do the low temp test in every device. they Spray a quick refrigerant in NFC/MCU/CAN, and get the SPI signal , you can review the SPI signal, could you help see any abnormal in any device SPI.
