11. Low Voltage and Over Voltage Detection (V
12. Detection of Abnormal State of Power Supply System (V
V
low voltage is detected.
• This Example circuit detects abnormal low/over voltage of power supply voltage and is indicated by LED
• The detection levels of low/over voltages are determined by V
