bq500210 or bq500211 with input of 5V?
I would like to create a little wireless battery charger with input 5v.
My question is about the trasmitter.I have seen that bq55210 has input of 5V and bq500211 has 19V.
Can you explain me about the difference of the pin "pwm_b" (13) in bq500210 and bq500211?
The bq500210 generates the dual pwm as bq500211?
If i use the schematics of bq500211 EVM (http://www.ti.com/lit/ug/slvu536/slvu536.pdf) with input of 5V, i can mount on the board only the bq500211 or also the bq500210 indipendently?
The bq500210 device will support a Wireless Power Transmitter design with 19V input. Power switching section of this design is a Half-H bridge using two switch fets. With one PWM drive signal out of the device.
The bq500211 device will support a Wireless Power Transmitter design with 5V input. Power switching section of this design is a Full-H bridge using four switch fets. With two PWM drive signal out of the device, one for each side of the H bridge.
Design spins of the bq500210 to operate directly from voltage other than 19V are not recommended or supported by TI. The same is true for bq500211, only 5V input should be used.

Bill, thanks for your quick reply.
my question is a simple curiosity to create a prototype to test the technology and are interested in bq500211 as a solution with low-voltage input.I saw (# http://www.ti.com/product/bq500211?qgpn=bq500211 buy) it is more difficult to ask samples of bq500211 than the bq500210, correct me if I'm wrong.
I guess that's because it is newer product than the another comp.
If I wanted to buy some bq500211 bq51013A and where can I buy them (now I have only seen Mouser and DigiKey).
