Hello,
The last page of the LTC2875 Data sheet (Rev A) shows a circuit for IEC Level 4 protection against surge, EFT, and ESD. 3 Questions:
we are using LTC2875 for Devicenet Master and there are many error and wafeform ringings in industrial environment(very noisy).
however, there are no error after i've just changed CAN transceiver as PCA82C250(NXP)
same product, same circuit, same environment…
Can LTC2875 communicate at 250 Kbps?
What is the data range?
Hi Kaino-san,
The bus fault tolerance is largely related to process on which the transceiver is fabricated. ±36V should be sufficient fault protection for shorts to 12V and 24V supplies. If greater fault tolerance is required, the LTC2875 with ±60V…
Hi Sabastian,
Its true the dominant state is higher power, but the larger concern may be a continuous dominant state blocking CAN bus traffic. Other nodes cannot overwrite the dominant state on the bus if the condition is allowed to persist.
Typical causes…
Hi lijie,
I did some asking around and unfortunately did not find external components that have been evaluated specifically with the ADM3053. I can point to the LTC2875 datasheet, section "Auxiliary Protection for IEC Surge, EFT and ESD" for general guidance…
Hi lijie,
I would expect the protection components would not interfere with communication. But this list of protection components form the LTC2875 datasheet have not been tested with the ADM3053 transceiver. The two transceivers are different, and these…
