Hello,

Unfortunately we have not characterized this device above 85 C since it was not intended to operate above this level.  In some of the typical curves beginning on page 8 of the datasheet you can get some idea of how different parameters vary with temperature, though.

Thanks, Max

I couldn't find the max junction temperature of the TCA6424A. can you find out the value.

Yesaihu,

Are you looking for the absolute maximum junction temperature or the recommended max?

For recommended, we typically will add 5C to the ambient recommended temp as our devices have low power dissipation. This would provide us with a 90C junction for recommended.

For absolute, if you use the device above 3.6V then we have a hard limit of 105C.
