To whom it may concern,
I'm trying to evaluate bq33100 with EVM. When the EVM is powered on, some initial values are different from the Doc. of bq33100.
After being powered on, the function that automatically turning off the pin of CHG FET does not work unless FET Action is set.
So does the Fault pin.
Thus, if bq33100 is designed with a system of FPGA, the entire protected function is shut down and will not take action to harsh conditions, such us Over Voltage or Over Current, at the first time before the system set corresponding bit to turn on the protected function. What should I do to avoid this situation? Do I have to design a external circuit to limit the voltage and current to prevent the hazard?
