Hii,
In TLE9471ES when VCAN_UV is touched off the TLE9471ES will disable the CAN transmitter.
That means the CAN event is still in working condition.
So, my question is when the VCAN_UV fault is still present can the CAN signals be dependable to read use for further action?
Thank You
Hi, It was mentioned in the datasheet that In CAN take Only Mode (RX only), the driver stage was deactivated, but the event is still operational. This mode is accessible by an SPI command in SBC Normal Mode and in SBC Stop Mode. The transceiver is still correctly working in Receive Only mode if VCANRead more
Hi,
It was mentioned in the datasheet that In CAN take Only Mode (RX only), the driver stage was deactivated, but the event is still operational. This mode is accessible by an SPI command in SBC Normal Mode and in SBC Stop Mode. The transceiver is still correctly working in Receive Only mode if VCAN isn’t available because of an independent receiver supply. regarding UV in CAN normal mode, we’re checking the integrated CAN receiver circuit of the SBC to get other details.

Hii,
Thanks for your query.
The voltage at the CAN supply pin is covered in CAN Normal and Receive Only Mode. In the case of VCAN
Undervoltage signalization via SPI bit VCAN_UV is touched off and the TLE9471ES disables the transmitter stage.
If the CAN supply reaches a higher position than the under-voltage finding threshold (VCAN>VCAN_UV,r), the transceiver is automatically switched back to CAN Normal Mode.
The under-voltage finding is enabled if the mode bit CAN_1 = ‘ 1 ’, i.e., in CAN Normal or CAN Receive Only
Mode. As the Receiver is also powered by the VCAN, in case of insufficient supply, it may not transmit the signals correctly and admit them correctly. PFA for further information.
