9. Dual (Positive/Negative) Power Supply Voltage Monitoring (V
10. Reference Voltage Generation and Voltage Sagging Detection
(1) 9V Reference Voltage Generation and 5V/9V Monitoring
Monitors a 5 V and a negative (any given level) power supply. R
In cases where V
In the above examples, the output voltage and the detection voltage are determined by the following equations:

Detection Voltage = V
Example if V
Detection Voltage = 7.2 V
Detection Voltage = (R
