BQ51050B Qi Wireless Receiver-A Qi Powered and Battery Charging Receiver NEW from TI

johnsocm

Hello World,

 

I just wanted to let you know that Rev 2 of both of my boards will be out very soon even though Rev 1 are about to be delivered and then tested. TI just came out with the BQ51050B Receiver and this allows us to have the Qi Receiver and the Li-Ion Charger in one Chip. According to TI, this allows up to a 60% less footprint! This will help costs go down significantly and this will also allow for either a smaller board, less components or BIGGER proto area.

 

I am going to integrate this new chip on both my Hot Qi Dog Cape and the Qi Lime Pi Shield. This is the device we have been all waiting for!

  • Hi Chad,

    I've got a copy of both documents and the Schematic on the EVM user's guide and at a passing glance many things don't yet match up.

    Amongst the mismatches, the product brief shows the bq51050B having BATT pin. The EVM shows that it has 4 OUT pins.

     

    What I'm about to say might be wrong. but here goes anyway.

     

    I've noted that the bq51050B outputs 4.2V @1A (max) on J3 whereas on bq51013A it outputs 5V @ 1A (max)

    The output goes from Pre-Charge mode (200mA) to Fast-Charge mode (1000mA) depending upon the state of the Battery.

    Charging will terminate (i.e. Wireless power stops) when battery has reached 4.2V.

     

    I can't see any DPPM (Dynamic Power Path Management) apart from the External Adapter (Non-wireless) input.

     

    I don't know what ramifications this has to any permanently connected downstream devices.

    I'll look into this in more detail later and for the time being I'll concentrate on completing my project.

     

    Cheers
