The VBATT voltage rises or falls and is output to VIN2.
When PGOOD2(int) is High, the power switch turns ON to
output the VO2_SENSE_IN voltage to VOUT2. If you turn
DDC2 OFF using the register, the power switch 2 also turns
OFF. Capacitance value which is connected to
VO2_SENSE_IN should be higher than the capacitor
connected to VOUT2.
POWER SUPPLY VO1_SENSE, VO2_SENSE:
NI_MH
The VBATT voltage rises and is output to VIN1. When
PGOOD2(int) is High, the power switch turns ON to output
the VO1_SENSE voltage to VOUT1. Capacitance value
which is connected to VO1_SENSE should be higher than
the capacitor connected to VOUT1.

Notes
28. All combinations of input are not included.
29. Operation is not guaranteed when VO1_SENSE input voltage is 1.8 V or lower. By connecting a diode between VIN1
and VO1_SENSE, VIN1 can output voltage higher (with the voltage difference Vf) than VO1_SENSE.
