Hi Team,

For the DS90UB928-Q1, is it possible to turn off the OpenLDI outputs and keep the I2C forward/back channel working?

If it is possible, can you please explain how to accomplish this?

Thank you,

Jared

There is a pin that can enable or disable the outputs, called OEN. After it is toggled High to enable the outputs, it is recommended to perform a digital reset by writing 0x01[0] = 1.

Thanks,
Jason

Awesome, thanks Jason! So even when the OpenLDI output is disabled, the I2C back and forward channel will still work?
