There is no I2C master device in my design. Can I continue to use the autonomous function?

Hi Nuo,

TPS23881 needs SRAM to be loaded to be IEEE compatible. What's the required port power? If it is <=30W, you can use TPS23882B as it has autonomous mode. Thanks.

Best regards,

Penny

The required port power is 90w for my design。If I don't need to go through IEEE compatibility, can I still use automatic mode ？

Hi Nuo,

If you don't care about IEEE compliance, you can use TPS23881 with autonomous mode. Please request FW access through TPS23881 product folder. Thanks.

I would like to know whether the firmware must be downloaded to use TPS23881, or a version of firmware has been loaded before the chip leaves the factory .

Hi Nuo,

The chip has ROM code already to be functional. As I mentioned above, if you want to be IEEE compliant, the SRAM code must be loaded. Please check the SRAM code advisory in the mySecure folder and understand the limitations of just running the device with ROM without loading SRAM code. Thanks.

How can I access the mySecure folder and get the SRAM code? I don't know the method, can you provide it to me directly 。This is what bothers me。I tried to log in and apply with my account。
