2. GND: Ground reference
3. RESET: Active-low reset output
4. MR: Manual reset input

Functional Features

• Monitors the supply voltage and generates a reset signal when it falls below the specified threshold.
• Provides a manual reset input for system initialization.
• Offers a wide range of reset timeout periods to suit different application requirements.

Advantages

• Reliable voltage monitoring ensures proper functioning of electronic systems.
• Low power consumption helps in energy-efficient designs.
• Wide operating voltage range allows compatibility with various power supply options.
• Small package size enables space-saving designs.
