TCAN3403-Q1: TCAN 341X IC circuit design

Part Number: TCAN3403-Q1
Other Parts Discussed in Thread: TCAN3414, TCAN3413

Tool/software:

I am using TI's TCAN341X to design UART to CAN signals. I am connecting STB and SHDN to ground. I can see the signal input on the TX side. But there is no signal output from CAN H.

What is the problem? Is it a circuit design error?

Here is the circuit diagram

Hi Sky,

Are you using TCAN3413 or TCAN3414? SHDN is only on TCAN3414, if you are using TCAN3413, the VIO pin needs supply.

Can you provide a waveform just for us to ensure the device was in normal mode? Your schematic looks good so I would like to check the voltage level.

Regards,

Sean

Hi Sean

Thank you very much.

I've solved the problem.

You are right that the pin needs to be connected to Vcc
