Part Number: TCAN1042-Q1
Other Parts Discussed in Thread: TCAN1043

hi Team,

customer checking for parts that be similar to TCAN1042-Q1 in VSON package and lower power consumption. 

please help recommend for such part.

Thanks

    Hey John,

    I've assigned one of our enginners to take a look at this question. I suspect they will give you an answer by tomorrow.

    Thanks,

    Hi John,

    When operating in Normal Mode, the TCAN1042 performs at the same levels of power consumption as other TI device families:
    Normal Mode (dominant bit) = maximum 70mA
    Normal Mode (recessive bit) = maximum 2.5mA

    When operating in Standby Mode, the low power mode of the transceiver, then TI offers one device with lower VCC/VIO current than the TCAN1042. This device is the TCAN1044.

    TCAN1042 Standby Mode (VCC only) = maximum 22uA
    TCAN1042 Standby Mode (VCC/VIO) = maximum 5uA (VCC), maximum 17uA (VIO) [maximum 22uA total]

    TCAN1044 Standby Mode (VCC only) = maximum 12uA
    TCAN1044 Standby Mode (VCC/VIO) = maximum 1uA (VCC), maximum 11uA (VIO) [maximum 12uA total]

    The TCAN1044 is the lowest power 8-pin can device that TI currently offers. TCAN1044 is available in the 8-pin VSON package.

    You may also consider the TCAN1043, which is a 14-pin CAN solution that allows system-level power savings by offering Sleep Mode. Sleep Mode allows low quiescent power consumption at the transceiver level, but also provides an enable pin for the system-level power regulators. This means that the entire system may enter a low power mode when CAN traffic is not being processed.


    Do these recommendations help?
