Correct pin function for EN6363QI pin 17

The EN6363QI datasheet defines pin 17 as a PVIN pin. But the schematic symbol from Intel and the Evaluation Board User Guide's schematic show this pin as NC. In addition, the Evaluation Board User's Guide schematic connects pin 17 to the PVIN net (and the same net the other PVIN pins are connected to). So I suspect the schematic symbol is wrong and the datasheet is correct. But I'd appreciate a confirmation on this.

 

Thanks,

Hal

Hello Hal,

 

We are really sorry for this error.

Actually pin17 is not internally connected, so it does not matter if connected to PVIN or left floating.

The datasheet was updated to re-name that pin as PVIN since the layout and the schematic show that pin is connected to PVIN.

But unfortunately Enpirion team missed to update the schematic symbol and the user guide schematic too. I will sent a request to update the schematic symbol and the user guide to be consistence with the datasheet.

 

Thanks,

Mostafa

Hi Mostafa,

Thanks for getting back to me. Just out of interest, does this device share a similar package and pinout with any other Enpirion devices? If so, how do those handle pin 17? It looks like I have a choice to either connect pin 17 of this device to PVIN or to leave it floating. If these similar devices require the pin to be connected to PVIN or to leave it unconnected, I will follow those to allow for a migration path.

 

Thanks,

Hal

Hi Hal,

 

Yes, EN6363 is pin to pin compatible with EN6340 and pin 17 is not internally connected for both of them. so both of them have same schematic and layout.

EN6363 is a 6A device but EN6340 is 4A device.

 

Thanks,

Mostafa

OK, thanks for the quick reply. Very helpful. Good to know I can migrate the design to a lower current part if need be.

 

Regards,

Hal
