Hello,
I have an evaluation module, using the bq20z80 (v. 102) and I have programmed the device and am trying to run the load cycling, but even though the discharge FET's are open, I can't get it to support any kind of load. I went through and used the BQEasy setup, and also tried manually setting the dataflash settings. Both yielded the same result. I also tried sending the device command 0x0021 to make sure it was in fuel gauge mode. I would also like to note that even though there is no charger hooked up and it is completely charged, it is still showing the charging voltage (and a constant current of +4mA, which I can't calibrate out because you are supposed to put a 2A load to calibrate the current), which in conjunction that the charging FETs are also set (the status flag is red). It shows no failures, and otherwise everything is set perfectly fine. Any clue why this won't let me discharge and cycle the battery?
Any suggestions would be much appreciated.
Allen
