    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...

    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...

    The bq51013 does NOT have a min power termination; the device could operate at a low or no load current. We do have options for terminating the device at low current using an external circuit or future spin of the device. Best Regards Bill

    To improve efficiency and provide good load transient response voltage into the LDO (V-RECT) will change with output current. This will result in a change in efficiency as load changes, improving as load increases. Also below 225mA the synchronous rectifier is operating in a half synchronous mode...

For the YFF package the Case Top is the die substrate, thermal resistance will be very good. But from a practical stand point cooling will only...

    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 Lingyu Sorry you are having problems with the Gen2 kit along with the Gen1 kit. Could you look at the 19V input to the transmitter EVM. Verify that it is solid with now dips, voltage must be 19V +/- 1V. Some customers have had problem with input power supplies entering current limit during...

    Hi Bill, I have tested the input voltage supply with scope. The result is: 1. Average high and low are both 18.5V 2. Max high is 19V, and min low is 17.9V So I think the input voltage supply should be stable. And the thing is I have tested the two generations of transceiver kits with different...

    Hi Bill, Finally solved, the JP3---TS did not connect to DIS. After connecting them, the receiver works. I have received all your new kits, and I will try out later, hopefully could get positive results. Thank you !

    Very good. JP3 controls the external temp sense option of the bq51013. With shorting jumper in the DIS position a fixed resistor is use to set value of the TS pin to a safe value with no input or connection to J5, TS connection. With shorting jumper in the EN positions an external NTC thermistor connected...
