TLC5940 - thermal pad electrical connection

andrew berry

My assumption is that the thermal pad in the surface mount packages should be connected to ground, but I haven't been able to find anything that comes right out and says so. Am I right? Is it in the datasheet somewhere and I'm just blind?

Thanks.

Hello Andrew,

You are right, the thermal pad should be connected to GND if possible. In the datasheet you can find some typical characteristics for ICs where the pad is not soldered.

Best regards,

Thank you!

Just for the sake of my sanity, is that actually indicated somewhere in the datasheet? Because I couldn't find anything that mentioned the electrical connection of the thermal pad.

Hello Andrew,

No, it is not indicated in the datasheet. It is indicated in the EVM user's guide in the product folder.

Best regards,
Brigitte
