Hi,

we have just released our manufacturing documents for producing a board using the BQ51013 chip.

Now we usually go trough all the documents available to verify twice that correct drawings are sent before producing the boards.

We found in the documentation of the BQ51013EVM-725 at paragraph 6.7 Disable Shutdown that the EN2 pin was to used to disable the wireless power transfer.

Is this an error since we used the definition specified in the BQ51013 specification, which tells that the EN1 will controls the wireless power and the EN2 controls the Adapter power. This information is repeated in paragraph 4.2.1 and 4.2.2 of the BQ51013EVM-725.

It is important for us to get soon the right information since we actually are on the point to launch a production. 

Could you please confirm us is the EN1 pin is the one to use to disable/enable the wireless power transfer.

Thanks for your support

    Hi

    The description of EN1 and EN2 in the bq51013 data sheet is correct.

    The description of EN1 and EN2 in bq51013EVM-725 User’s Guide in paragraph 4.2.1 and 4.2.2 are correct.

    The description of Disable Shutdown in bq51013EVM-725 User’s Guide in paragraph 6.7 should read JP1 (EN1), not JP2 (EN2).

    The User’s Guide will be change in the next revision.

    Best Regards
