TPS55289EVM: Unable to connect with USB2ANY

Hi,

Thanks for reaching out.

What is mode pin connection now? Have you tried with auto connect to exchange the I2C slave address?

BRs,

hello

I also tried automatic connection.

Also, there is no change even if the PIN is changed to VCC or AGND.

We will send you the communication waveform.

Is there somewhere else to check?

Hi,

Is the VCC voltage correct? Can you also take a photo of the tested EVM?

BRs,

Bryce

hello

VCC voltage selects internal LDO.

When I measure the voltage, there is no voltage.

Does this EVM require external power?

I will send you a photo of EVM.

sorry

I said above that there was no VCC, but it was a measurement error.

I was able to confirm that 5V was output.

Hi,

If VCC output 5V, then it should be ok to for I2C connection.

Can you input the I2C address to 0x74 and have a try?

BRs,

Bryce
