Hi,

Sorry for my english, but I don't understand how to send a "End Power Transfer with Charge complete"?? I use a BQ51013EVM-725 and a BQ500210EVM-689

if the TS pin is connect to the gnd, I have the red led on the BQ500210EVM-689!!!

I just want to send a End Power Transfert : charge complete with the BQ51013EVM-725 and watch the green led on the transmitter

Thanks for your help

    The TS pin can be used to send two types of End Power Transfer commands. One is Overtemp Fault, EPT03 and the other is charge complete EPT01 see table 2 in the data sheet.  

    A low voltage at the TS pin is an overtemp and it will set a fault condition on the Transmitter.  This is the Red led that you observed when the pin is grounded.

     

    If the pin is pulled high it will send a charge complete (EPT01).  A high is typically the battery voltage of 4.2V.

    Also see bq51013A device. This may be a better device to use for production, but PCB changes are required.

    Hello,

    What is the best solution you have right now for wireless charging (Transmitter and Receiver)?

    I saw some products on you website but there are lot of options but i dun know which is you latest and best one, which needs less circuitry other then the IC itself.

    Thank you
