PCA9536: The thermal information and power dissipation

Part Number: PCA9536

Hi Team,

Please help to confirm the thermal information of PCA9536DGKR. Data sheet doesn't show Θjc.

Also, how to calculate its power dissipation? Please kindly provide the formula.


  • Hi Daniel,

    We are working to get you this information. It may take about a week to generate the thermal resistance.

  • Hello Daniel,
    I submitted the thermal model request and we should get it by the end of the week. The power dissipation is going to be heavily dependence on how you setup the IOs. Do you have a schematic of the proposed implementation? I can do the calculations for you and show you how to do them. Power dissipation is simply difference between Power In and Power-Out, but of course their are more details to the calculations but give your schematic and can show you how to calculate it.

  • Hello Daniel,

    Here are the thermal model numbers. 

    Do you have circuit diagram or schematic so I can give you a detailed description on how to calculate the power dissipation?  Let me know.
