20 / 38 page ![]() Analog Integrated Circuit Device Data 20 Freescale Semiconductor 18730 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. Table 11.
