I hope this message finds you well. I am reaching out with a query regarding the connection of pin VSS to pin COM in the IR21094 driver.

Could you kindly confirm whether it is standard practice to connect pin VSS to pin COM in the IR21094 driver? I am seeking clarity on this aspect to ensure the correct configuration and optimal performance of our circuitry.

Your expertise and insights on this matter would be greatly appreciated. Thank you in advance for your assistance.

Best regards,

Dear @Youcef_RZ ,

Greetings from Infineon.

COM is power return path and VSS is signal return path.

both cannot be connected together near Gate driver IC.

in the complete system level schematic  common power return and common signal return can be combined at single place in case of non isolated systems.

 

Thank you.

Best Regards,

Siva Naga Malleswararao.
