i.MX6DQ Junction to Case.

Hi community,

 

I have a question about i.MX6DQ thermal resistance.

Please see Table 5 in IMC6DQCEC Rev.3.

I understand junction temperature is present by the following equation.

 

"Junction to Case" (< 0.1) = ("Junction Temperature" - "Case Temperature") / "Power consumption" : [equation 1]

=> "Junction Temp" = "Junction to Case" / "Power consumption" + "Case Temp" : [equation 2]

 

Then, should I assign "0.1" to "Junction to Case" in equation 2 to calculate "Junction Temp"?

Or can I think "Junction Temp" = "Case Temp" because "Junction to Case" is small value sufficiently?

 

 

Best Regards,

Satoshi Shimoda
