Hi,
I am trying to use Bq24630EVM to charge an 8-cell LiFePO4 battery. I have multiple such batteries connected in parallel, and was trying to provide a 10A charging current. I am using a 28V/14A power supply as the adapter source, and a 3.5 ohm power resistor as the system load. I modified R25 to 1.5Mohm, R7 to 560k ohm, R12 to 154k ohm to get a 10A charging current, 14A adapter regulation current, and 28V battery voltage. Bq24630 chip caught fire... Can you tell me what is wrong here? Does this have something to do with the Eval Board or the fundamental limitation of this chip?
Best,
