TCAN1043-Q1: TCAN1043ADMTRQ1 - Vsup decoupling cap

Jose Maroto

Part Number: TCAN1043-Q1

Dear team,

Could you please help with question below:

"We are studying to use TCAN1043ADMTRQ1.

You are recommending to use  100nF as decoupling capacitor for Vsup in your datasheet .

In our actual design we are using only 10nF as shown in the below schematic red rectangle . Can we keep only this 10nF?

 

"

Could you please provide feedback?

Thanks and rgds, Jose

    Hi Jose,

    It would depend on the system environment / supply noise levels and would recommend to verify per the actual system needs.

    However, would strongly suggest ensuring the recommended if / when unsure, thanks.

    Best Regards,

    Michael.
