PCA9544A: Thermal Information (Theta JC and JB)

Jejomar Ildefonso

Part Number: PCA9544A

Hi Team,

Our customer is requesting for the thermal information (Theta JC, Theta JB and max junction temperature) of PCA9544APW, specifically for the PW package (PCA9544APW).

Would you be able to provide the needed information?

We would really appreciate any response. Thank you so much in advance!

Regards,

Hello Jejomar,

Below is the thermal model analysis:

For maximum junction temperature:

Recommended Maximum = ~90C

For absolute Maximum, I would recommend you keep the junction below 105C.
