TCAN1043-Q1: conformance test report

Part Number: TCAN1043-Q1
Other Parts Discussed in Thread: TCAN1043

Hi team,

One of our customers is testing the conformity of the TCAN1043DMTRQ1.


The RL used is 62 Ω and the dominant level is 3.12V. The RL=62Ω in the figure above corresponds to two voltage ranges, how should we tell if this test passes? And I would like to know why there are two parameter criteria? 

Could you please kindly help share the TCAN1043DMTRQ1 conformance test report since customer need to do some comparison?

Best Regards,

Amy Luo

    Hi Amy,

    The two datasheet parameters for differential output voltage are based to the normal bus load and extended bus load definitions in the ISO 11898-2 CAN standard document which lists these two characteristics as separate table items (table 5). 

    The output voltage higher than 3.0V in the normal bus load case is not expected, but is not concerning as a higher differential here is beneficial to the signal integrity of the system. The discrepancy may be due to a difference in measurement methods, load resistor variance, or a slightly higher voltage supply on Vcc. 

    The C&S conformance test reports for all of our CAN transceivers can be found on the trx/ sharepoint in the relevant device folder under "EMC test reports". The folder for TCAN1043 is linked below:

    Let me know if you have any more questions. 

    Regards,
