See Table 8 for details.
When disable IC1 mode is active, the VINx supply must always be connected and the supply voltage level must fulfill the following condition: V
When disable IC1 mode is active, the back gate of the LDO FET is not controlled. If the VINx pins are not connected to any voltage supply, the body diode of the LDO
FET can become forward biased and the voltage at VINx is V

Low = LDO enabled.
High = LDO disabled. In addition, when EN_CHG = low, the
battery isolation FET is on; when EN_CHG = high, the battery
isolation FET is off.
