FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
POWER SUPPLY VO1, VO2: LI-ION
The VB voltage falls and is output to VO1. When using
Li_ion, duty limit due to DTC1 is not applied to the switch.
When RSTO2B(int) is High, the power switch turns ON to
output the VO1 voltage to VCC1. Capacitance value which is
connected to VO1 should be higher than the capacitor
connected to VCC1.
The VB voltage falls using only the internal transistor and
is output to VO2. When using Li_ion, duty limit due to DTC2
is not applied to the switch, and DW_2T and DW_2B are Low.
When RSTO2B(int) is High, the power switch turns ON to
output the VO2IN voltage to VCC2. If you turn DDC2 OFF
using the register, the power switch 2 also turns OFF.
Capacitance value which is connected to VO2IN should be
higher than the capacitor connected to VCC2.
