Tool/software:
Hi
TPA626 and ISO1541DR in the loop When the system is not powered on, the voltage of the power supply pin is about 1.6V to 2V. The IIC communication failure of TPA626 may cause the system to fail to start normally.
In this case, what will be the adverse impact on the isolation chip？
Please help to confirm, thank you
Hello,
Thank you for question.
The device won't be damaged if the supply voltage is between 1.6V to 2V. However, we do not guarantee the normal operation of the device, as it is not under the recommended operating conditions. Please see absolute maximum ratings and recommended operating conditions shown below:
