The BQ25723 chip supports both CC and CV charge mode by setting it with CELL_BATPRESZ voltage and register. For 2-phase battery charge cycle, the charging start from CC then switch to CV.
How the BQ25723 switch the charge mode? Does it switches CC to CV without MCU involved? Or need the MCU to switch the mode? If the MCU register operation needed to switch the CC to CV,
how the MCU telling the battery voltage is reached the 4.2V to change the mode?
Or this chip doesn't design for 2-phase charge?
