UCC29002: Component tolerance

Part Number: UCC29002

Hi Team,

For UCC29002 design, what % of component tolerance should I use? Especially sense resistor?

Thank you.

Best regards,

C.T.

    Hello C.T.

    Most applications use 1% or less component tolerance for the current shunt.

    Because the sensed voltage across the shunt  is usually fairly low it is very important that due diligence is paid to component placement and pcb layout.
    This greatly affects current sharing accuracy.

    Regards
