Functional Features

• Power supply voltage monitoring
• Power-on reset generation
• Manual reset input for external control
• Reset output signal for system initialization

Advantages and Disadvantages

Advantages

• Wide operating voltage range allows for versatile applications.
• Small package size enables space-efficient integration.
• High accuracy and reliability in power supply monitoring.
• Power-on reset ensures proper system initialization.

Disadvantages

• Limited threshold voltage options may not suit all applications.
