  • Forum Post: distance between primary and seconday coils

    Ben M
    Hi, all, I am trying to use bqTesla to power up a MSP demo board. Is there anyway that I can extend the range between the primary coil and the seconday coil to a few cm? Currently it only works when they are about 5 mm apart. Thanks a lot. Ben

    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...

    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...

    RVG
    Hi, Need some advise on the BQ51050B, 1) How to we determine the %Vcold and %Vhot? Also, based on the diagram, there is R1, R2, R3 and RNTC. However R2 should be fixed as 20K internally. How does the mathematics involve the R3, RNTC and R2? What about the R1? How to get the R1 and R2 value from the...

    Hi Tahar, 1) I couldn't agree more on the Iq of 20uA if the WP is disabled with 4.2V battery. However, what about the Iq at 3.6V? Pls find plot as below. 2) Need your help to advise more on the Vhot and Vcold. What does the V 10c and V 45c means? So if i were to set the Vcold as 10degC, i input...

    Hi Tahar, Pls help me to understand the below 2 mathematics. How does the values highlighted relates to the formula above? So the V10c refers to VT2. What does the VTS 40% -50% means? What does the %VTSB means? I know the IQ @ 4.2V is within specification. Any advise on the IQ @ 3.6V = 26uA?...

    Hi, I am trying to use off the shelf A10 coil (24uH) as the receiver for a WPT solution. I am using bq51013 at the receiver side and bq500210 at the transmitter side.I use A10 coil at the transmitter side too. Every thing works fine until I react a load current of 600mA at which point voltage at...

    Shane Knapp
    What function does the cap on the OUT pin serve and how is it the value calculated? The pin description does not call for a cap but the EVM and Figure 2 of the BQ51013A user guide do. Please clarify.
