I would like to ask about the thermal characteristic of i.MX283.
My customer is evaluating MCIMX283DVM4B on his board and has a question on the thermal characteristics of i.MX28.
In their test, the temperature of i.MX28 surface reached 64 degrees C when the environmental temperature was 25 degrees C.
At that time, the usage rate of i.MX283 was 50%.
|CH||Simbol||measurement point||Temp. Deg.C||Estimated DegC in 45 DegC of environmental||Max.Ratings|
|CH1||U1||surface of i.MX283||63.8||84.1||70|
The power consumption of DC24V on the board is 140-150mA.
Is that reasonable?
Do you have any ideas to lower the temperature?
Estimated temp number in the 45 degrees C of the environmental temp is 84 degrees C, and the number exceeds the maximum ratings.
The customer has a doubt whether the temp really can reach to 64℃ even when the usage rate was 50%.
