  • Forum Post: bq500210 or bq500211 with input of 5V?

    Luca Pecchini
    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...

  • Forum Post: What is V-sense pin function of bq500211? Does V-sense will adjust PWM parameter and inflect power transmit efficiency?

    Joe Chen1
    I have the questions about bq500211 chip of wireless charging function, bq500211 chip has V-sense pin to detect transmitter input voltage and used it for efficiency calculations, but our circuit has two kinds of voltage of transmitters as 7V & 12V, should we use fixed 5V to separate voltage to give...

    Bill Johns
    A 10k resistor on pin 31 to ground is recommended. EVM is going through revision now and will have a resistor in this location.

  • Forum Post: bq500211 + A11 coil and WPC certification

    Frederic Vautard
    Hi, bq500211 can be used with A5 type coil and also A11 type coil. bq500211 is certified for WPC 1.0.3. However A11 type coil appears only in WPC 1.1.x specifications. So can a design based on bq500211 + A11 type coil be WPC certifiable ? Thank you, Fred.

  • Forum Post: BQ500210 operation at 12V

    Lee Coppins-Brown
    Hi We are completing development of a portable battery powered product which incorporates a BQ51013 receiver. We are now starting the wireless transmitter half and have a draft BQ500210 design based on the BQ500210 EVM. However, the hope was to adapt this to run at 12V rather than 19V, following...

    CWilson
    Hi, Must I use the BQ500211 or BQ500211A /5V version ICs) when I want to charge mobile phones, e.g. Nexus 4? Or can I use the 12V or 19V transmitter ICs? And will they provide longer range? What is the range of the different IC´s? I read that the "old" WPC stated 5mm for Qi-standard...

    Piotr Twardosz
    Dear all, I have designed a Qi charging system (using BQ51050) chip in which the receiver coil is placed on top of a LiPo battery. The battery is coin shaped cell enclosed between metal sheets. It looks like the following: http://i.ebayimg.com/t/Forerunner-405-405CX-Battery-LIR3048-Rechargeable...
