TCAN4550: Difference from transceiver + controller.

Guru 10385 points
Part Number: TCAN4550

Hi team,

My customer is also considering transceiver + controller.
Could you tell me the good points of 1chip of TCAN4550?

They are looking for a solution that consumes less current.
Is TCAN the best in terms of current consumption?

Sincerely.
Kengo.

  • Kengo,

    Currently, the TCAN4550-Q1 is the only SPI-to-CAN controller + transceiver on the market, so technically yes it is the best in terms of current consumption.

    Can you elaborate more on the customer's needs?

    Regards,

  • Hi Kengo,

    Apart from the typical advantages of integrated solutions like size and simplicity, combining both transceiver and CAN FD controller into a single IC allows black-boxing of much of the CAN-specific protocol. This can greatly simplify the software development by only requiring the microprocessor to configure and communicate through SPI transactions. It will also free up the processor to do other tasks while the dedicated IC handles CAN correspondance. 

    TCAN4550 features low power Standby and Sleep modes to reduce power consumption during idle states. The INH pin can also be used to control the supply to the entire node, saving power by shutting down the microprocessor and other devices until a wake event (locally or from the bus) signals to bring the node back online. The majority of power this device uses while active will the transceiver, and will depend considerably on the system load, communication frequency, and event data content. 

    Let me know if you have any more or more specific questions regarding TCAN4550.
