Hi, Tommy,

Some customers use this part for AC switch or input power monitoring in a creative way. Some of the pin were left open and some of the functions were disabled. Please note that the BQ24780s is validated in its standard configuration as implemented on the BQ24780s Evaluation Module. Customer modifications must be validated by customer.
