TCAN1051H-Q1: When will we use the silent mode

Part Number: TCAN1051H-Q1
Other Parts Discussed in Thread: TCAN1051-Q1, TCAN1042-Q1

Hi Team,

Could you let me know when will we use the silent mode(TCAN1051-Q1) and standby mode(TCAN1042-Q1)? 

Regards,

Roy

  • Roy,

    The silent and standby modes are meant for low-power use in the application. Standby mode uses a fraction of the current compared to normal mode by disabling the bus driver and receiver. Silent mode lowers the current consumption of the transceiver by disabling the bus driver, and only enabling the receiver, effective making the transceiver "silent" to the bus.

    Please let me know if you have any other questions.

  • Hi Eric,

    I understand that the difference between two mode, and I would like to know when will customer choose standby mode and when will customer choose silent mode for any specific application.

  • Roy,

    Standby is typically used in automotive applications where the portion of the car that the TCAN1042-Q1 is connected to is not being used, and thus does not need to be on. The entire CAN bus is put into a low-power mode and then waken up by a CAN bus wake-up pattern. 

    Silent mode could be used when the rest of the bus is still active but you want the node to go into a lower power state while still receiving messages from the bus to your controller. The controller could be configured to look for a specific message before it switches the device back to normal mode.
