About ADP1613 COMP pin absolute maximum rating

Hi Kikuchi-san,

Voltage should not go above 1.6V. It is not recommend to have other part of customer's circuit connected to this pin.

Hi Fil-san

Thank you for your reply.

Yes, COMP pin don't connected to the other circuit, just RC network.

But COMP pin voltage go to 2V at start up.

I would like to confirm about the COMP Clamp High Voltage function.

ADP1621 have this function.(Vcomp,clamp=2Vtyp, 2.1Vmax)

Do ADP1613 have the COMP Clamp High Voltage function?

Best Regards,

Kikuchi

Hi Fil-san

Than you for your reply.

Yes, COMP pin connected to RC network only in the customer schematic.

But COMP pin voltage go to 2.1V at start-up. Please see the following waveform.

I would like to confirm about the COMP Clamp High Voltage function.

Because ADP1621 have this function.(Vcomp.clamp=2Vtyp)

Do ADP1613 likely to have this founction?

Hi Kikuchi-san,

Let me verify with designer.

The Abs Max rating is an indicator of the limits to which any pin might be forced from the outside world.  It has most relevance to things like supply pins and input pins, where the customer is potentially driving pins. In the this case, COMP going towards 2V during startup is ok.
