Can someone explain the purpose of U11, U12 temperature sensor in IWR1443boost? Is that sue for correcting the VCO of IWR1443?, If not, can we remove them?

Thanks,

Hi,

These temp sensors are to measure EVM temperature for cases where heat might be an issue.

Hi Charles,

If the EVM have some issue, does the signal be feedback to the IWR1443 device or PMIC to do some adjustment or just use for trouble shooting?

Thanks

Hi,

You have to read the temperature via I2C and implement some algorithm based on the read

Hi,

I am asking if ti currently does any adjustment based on the temperature reading on IWR1443 EVM board with any lab. You do not answer my question.

Thanks,
