    Ron, Two channels of communication are redundant to each other. Some redundancy helps when secondary-side impedance-modulation communication excibits nulls of communication -- points at which amplitude of the signal received on the primary side drops to very low levels. It was experimantaly shown...

    Hello Janez, Thank you for showing interest in the BQ500110. The part can be used in other wireless power applications. You will still need using the commands defined by WPC standard to make your solution working. The operating frequency range will be limited to 110kHz--205kHz. The WPC 1.0 Part 1...

    Hello Janez, Frequency is not arbitrary set by the controller. Frequency is function of load and coupling between coils. There is no other means to change the frequency. By varying the frequency the output voltage gets regulated. The part is made to support the WPC spec that sets frequency...

    Hello Chad, The WPC communication protocol has provisions for propriatary packets that can be used to pass limited user information from the receiver to transmitter. What would be needed to have controllers on both sides of the wireless link capable interfacing these information. These are not...

    Hello Dean, All your observations are correct. The 0.4s repetition rate you observing is the right number. The WPC spec requires detection of the receiving devise in no more than 0.5s. Considering some processing time needed, the 0.4s ping repetiton rate has been implimented in BQ500110. The...

    Hello Vladimir and thank you very much for your informative response. Now that i know the BQ500110 seems to be switching the coil correctly, I have moved onto debugging the reviever side/communication channels. When I first place my reciever on the transmit coil (there is about 5mm spacer between...

    Just a follow up on the last post I made: I fixed the errors I had with my demodulator circuit and the receiver is now communicating with the transmitter. The 500110 is no longer indicating faults when i place the receiver coil closer than about 5mm to the transmit coil. The last problem with my...

    Dean, I glad you reselve most of the issues. Per WPC maximum guranteed distances between coils is 5mm. The distance should be measured from coil to coil. It means that plastic covers in TI bqTesla kit should be included into this 5mm. Can you provide the details how you power bq500110 up. Are...

    Hello E2E community, I am currently debugging a design based on the BQ500110-EVM and the BQ51013-EVM. When I apply power to the BQ500110 and probe the COIL_PWM pin I do see the three 100kHz pulses except they occur every 0.4 sec instead of 0.5 sec (EVM user guide states it should be 0.5 sec...

    Hello Kyle, You will find very little difference in efficiency if you use dielectric materials. Efficiency will degrade slightly when distance between coils increases. The WPC technology is not intended to cover distance substantially higher than 5mm. Any conductors or ferrous materials will...

    Bill Johns
    Hello Moshe The distance of 12cm is a little far for the present WPC standard. It may be possible to transfer some power but also the receiver has to send commands back to the transmitter through load modulation. If receiver cannot communicate with the transmitter power transfer will stop. The...

    Hello Alexander, The CoilDis function is used to dump the coil oscillation during Analog Ping. The function is only present in BQ500110 EVM and there is no such function in BQ500210. Making changes to the resistor value will not improve the operating range. There is no provisions in both controllers...
