Advantages and Disadvantages

Advantages

• Accurate voltage monitoring ensures circuit stability and reliability.
• Adjustable reset threshold provides flexibility in voltage monitoring.
• Low quiescent current minimizes power consumption.
• Wide operating temperature range allows for use in various environments.
• Small package size enables space-saving designs.

Disadvantages
