Hi,

Have you tried to write to other bits? What are you using communicate with I2C to the TPS389006-Q1?

Thanks,

Andrew

Hi Yicheng,

Also, what resistor value do you have connected to Pin 14? That determines the device address.

That way you can connect multiple devices to the same I2C line and monitor more voltage rails (if you need to for the application).

Thanks,

Andrew
