Hello team
I just wanted to understand how the polarity of CBOOT capacitor comes in series with reference voltage , during Low side MOSFET turned on CBOOT will charge to Vcc and to turn on the HS switch we need VBAT+VCC , Plesae refer the below image for my problem.


above mentioned polarity is not in series with CBOOT voltage , Please correct me if i am wrong.
If my question is valid then how both the voltgae CB0OT and V BAT will be series to add up the voltage, according to my understanding below mentioned image will add up the voltage

Please provide justification how the CBOOT voltage will come in series with VBAT boltage to boost the voltgae
