Hello E2E,

Customer is suffering the i2c bus latch issue by TLV320AIC3104.

They reserve a 0-ohm to disconnect the i2c interface of TLV320AIC3104 with i2c bus. the issue could be gone.

They just sent some dummy data and the issue could occur.

could we have anyway to fix the i2c latch issue on TLV320AIC3104?

how about keep TLV320AIC3104 in reset state until dummy data complete?

Sincerely,

Jason

Jason,

There are no known issues with the I2C bus of the AIC3104. The Customer can of course keep the device in shutdown by holding the reset pin low until this dummy data is complete. can they provide more details about this issue?
