• LTM2889

    1.The LTM2889-5 chip manual indicates that the VCC2 port can generate a current of 150mA.Is the current the output current obtained by removing the current required by the internal device? 2.According to the internal structure diagram of LTM2889-5, it…

  • LTM2889-5

    1.LTM2889-5芯片手册上表示VCC2口可产生150mA的电流,那么该电流是否已去除内部器件所需电流而得出的输出电流?

    2.根据LTM2889-5内部结构图,发现VCC内部只是接了一个电容到地,没有其他作用,因此该端口输出是否既可以选择输入+3.3V,也可以选择输入+5V?

  • Placement of 2 LTM2889

    Hello

    I am doing a layout PCB with 2 LTM2889. I followed the layout recommendation but because of lack of space, I place the LTM2889 facing each other one in the top layer and the other in the bottom layer.
    Could this generate problems of noise? Or is…

  • RE: ADM3055E - dc/dc converter with additional load

    The ADM3055E's internal dc/dc converter is intended to only supply its internal CAN transceiver and the aux digital output and was not intended to supply additional external loads.  This is why the use case of powering an external load isn't discussed…

  • RE: CAN FD on ADM3054 transceiver?

    Hi farah.mim,

    The ADM3054 is not a CAN FD isolated transceiver. The top speed is 1Mbps. 

    Check out the ADM3055E for CAN FD up to 12Mbps

    www.analog.com/ADM3055E

    Or the LTM2889 for CAN FD up to 4Mbps

  • Isolated interface chip with power supply

    The LTM2889-3 is suitable for my requirements, but the BGA package is not conducive to small-scale production. Is it possible to recommend SPI isolation with a powered isolation chip? The final implementation of isolated CAN. My 5v power supply is used…

  • RE: ADM3053 interface protection

    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…

  • RE: ADM3056EBRIZ - Isolated Power for VDD2

    Hi Selvaraj, 

    If there is not power available on the bus side, then an isolated power supply from the logic side will need to be provided. 

    The ADM3055E and ADM3057E have an integrated isolated dc/dc converter to supply the CAN FD transceiver. When there…

  • RE: ADM3053 baud rate problem

    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…
