Part Number:BQ76930
Hello.
1.I have a question about the CHG mosfet(Q1) drive,in the figure 9 we can see that the chg FET drive circuit take "GND" reference for grante,the chg output connect to the gate of Q1,when without external load,the source of Q1 is floating, i think because of the source of Q1 and the chg FET drive circuit not reference for a same grante,the Cgc capacitance of Q1 has no charging loop,so Q1 can not be turn on.Who can tell me the working principle about this circuit?
2.Is there any MOSFET drive IC used for BMS low side mosfet?bq76930 drivecapability is not enough.
