Part Number: SN65HVD32

Hi Team,

We received PCN letter.

Then, Thermal Information of SN65HVD32DR is changed.

Could you please let us know why Thermal Information was changed?

Regards,

Sometimes, thermal information changes because TI did better measurements or improved the computations.

But this is not the case here. The PCN tells you that there is a new fab that also uses a new die. So the device itself has changed. Old chips are described by the old thermal information, new chips are described by the new thermal information.

Hi Hide

Its a new die so thermal impedances will change as the physical die is different - and that is why the datasheet thermal impedance values changed.

Please let me know if you have any other questions!

Best,

Parker Dodson
