FUNCTIONAL DEVICE OPERATION

OPERATIONAL MODES

Figure 9. Reset Timing Diagram

POWER SUPPLY VO1, VO2: NI_MH

The VB voltage rises and is output to VI1. 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 rises or falls and is output to VI2. 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.

Notes

29.

Operation is not guaranteed when VO1 input voltage is 1.8 V or lower. By connecting a diode between

VI1 and VO1, VI1 can output voltage higher (with the voltage difference Vf) than VO1.

30.

All combinations of input are not included.
