Voltage clamp triggerrd by the voltage at Rcomf

Hi toapex,

I'd have to say that there is no "D version" in production for MAX32010. I've checked and there is no resistor between SENSE and RCOMF pins on the die. For most cases, the VCLMP will respond to the voltage at RCOMF pin since these two nodes are internally tied together as you see on the page 17 block diagram. We'd probably remove that resistor and the note about the D version from the datasheet document.

The only time RFS (which is included in the D version and which again is not available for purchase) might make a difference in the voltage clamp operation / behavior is when there is significant voltage drop in the external path between the SENSE pin to the RCOMF pin due to large current flow or resistance between traces and through PCB vias. I wanted to ask if that is the situation you have on your application where you're seeing a significant voltage difference? If so, there is always the possibility of adding an external resistor between SENSE and RCOMF since both pins are externally accessible.

Hooman

OK， thanks
