I'm using BQ25792 to charge my 14.4V battery in 4S mode (PROG connected to 18K). when i am giving the input voltage 20V at VAC1 / VAC2 , the system voltage was not regulated to 12V. it was approximately equals to VBUS. Battery voltage was also equal to VBUS (19.6v).
There is no TS ERROR. CE pin was connected to ground. battery not connected. I2C operation was successful. I am able to read and write the registers. but the voltage was not regulated to SYSMIN (12V) why?.
Please Reply me.
