Other Parts Discussed in Thread: TCAN1043, TCAN4550, ISO1042-Q1

Hi Team,

I would select a TI CAN bus transceiver.  I want know what  have advantages compared to NXP CAN bus  transceiver.

    Hello,

    Thanks for coming to E2E to learn about TI's CAN portfolio. In general, TI's TCAN1042/1051 and TCAN1043 have better EMC performance with and without a common-mode choke. We also have slightly better integrated ESD protection in some cases, and there are versions of TCAN1042/1051 and TCAN1043 that have bus fault protection ranging +/-70V.

    We have the TCAN4550 SPI-to-CAN controller plus CAN transceiver integrated into one package, which NXP does not have in their CAN portfolio.

    We also have a family of 3.3V supplied CAN transceivers, the TCAN33x family, which again NXP does not have.

    Can you give a little more detail on what kind of CAN transceiver you need?

    Regards,

    Hi Eric,

    My company want design OBU (ElectronicTollCollection) .We need CAN bus transceiver communicate with S32K （NXP）. NXP suggest CAN bus transceiver  is  TJA1052IT. Have  TCAN4550 advantages and disadvantages contrast with TJA1052IT? 

    Thanks

    Hello,

    These devices are quite different in what they offer. TCAN4550 is a SPI to CAN device with CAN FD controller and transceiver integrated into a single IC. This device allows a microcontroller to be configured and interface through a SPI line and TCAN4550 will handle CAN-based control and protocol. TJA1052 is an isolated CAN transceiver and requires a controller to properly interface with a CAN network. TCAN4550 does not provide galvanic isolation.

    A similar device in TI's portfolio may be ISO1042-Q1. I'm personally not too familiar with this device, but a quick look at both devices datasheets shows that ISO1042-Q1 offers a greater Absolute Maximum Bus Voltage of +-70V. 

    If there are other specifications that are important to your design, let us know and we may be able to recommend a better fit. You can also type in the device name into the search bar at ti.com  to find similar devices made by TI (often best to use generic names i.e. leave out the "IT" suffix).
