Part Number: BQ51050B Other Parts Discussed in Thread: BQ51013A , BQ51013B Hi.
We want to develop some products with wireless charging and we plan to use BQ51050B on them, but I need help for design.
First I will develop a schematic and a simple board…
Part Number: BQ500210 Other Parts Discussed in Thread: BQ51013A , BQ500511A , BQ51013B , BQ500212A Hi,
are the BQ500210 and the BQ51013A, EN303417 qualified? If not, do we have solutions that are?
Thank you, Stefan
Hello
We have not released an EVM or reference design for the BQ51013B with QFN package.
But from a layout standpoint the BQ51013A and BQ51013B are the same. We did release a QFN EVM for the A version, see below link:

Hi John,
These parts are bq51013A's.
The CHG/ pin is tied to a 10K pull-up to 3.3V and is being monitored by a uP.
With no field applied to the pickup coil and with no other voltages applied to the BQ51013, CHG/ is pulled hi. When a charge field…
Viggo,
Same answer for the bq51013B. There is no minimum load current for the bq51013B.
The bq51050B minimum load is set for accuracy limitations. Setting the charge current below 500mA will still function, but over a large volume, the programmed…
Hello Nick
Take a look at TI Design TIDA-00318 it is a good starting point that uses the BQ51003 and BQ2510X.
The BQ51003 is a 500ma version of the BQ51013B. Note that BQ51013 and BQ51013A are NRND. Latest version is the BQ51013B and active.

Hello Seth,
The Wireless Receiver device is able to communicate with the Transmitter even though the battery is drained. When placing the RX on the TX, the TX induces a voltage in the RX coil which supplies the RX and allows the device to communicate…
Andrew,
One more thought. If you have an bq51013A EVM you should measure that on the transmitter as well to see if there are differences between your board in standby and the EVM.

Dick
