currently i am testing on bq25046evm-687 with bq500110evm-688. the problem is the receiver could not work properly with resistor that lower than 60 ohms, the system will be unstable and the current jump up and down quickly. I have tried to connect receiver to a cell phone also, the problem is the same, the system could not provide current more than 100mA whereas you declare the max output current will be 1A in your manual. So what could be the cause of this problem?
Sorry to hear that you are having difficulty with the EVM.
It should support the load you are describing but the problem could be receiver or transmitter. I could send you know good units.
But bq25046 and bq500110 are our first generation units and they have been replaced by bq500210 and bq51013. It would be better to evaluate those units for you application.
Contact me though the conversation option of the forum for more details.
