Tool/software:

Hi Team,

I am using TPS546E25 EVM in LAB. When i try to load current more then 1.2V@30A from E-Load. I can see in GUI Monitor TAB Current Graph Start toggling. 

Do i need Calibrate IMON_CAL[MFR14] FOR 50A?

What should be the IMON_G value for 50A of current so we can see right GUI current.

Many Thanks

Rajat

    Hi Rajat,

    What you are seeing here is related to a minor digital bug we had in first IC silicon samples. In the newer revisions of the TPS546E25 IC, this issue is resolved and can properly see above 30A on the GUI Monitor. Please disregard this, as it is taken care of in newer TPS546E25 IC's.

    Hope this helps

    Thank you,

    Calan
