Detailed Pin Configuration

ADM809LARTZ-REEL has three pins:

1. VCC: This pin is connected to the power supply voltage.
2. GND: This pin is connected to the ground reference.
3. RESET: This pin outputs the reset signal when the monitored voltage falls below the threshold.

Functional Features

• Monitors the power supply voltage continuously.
• Generates a reset signal when the voltage falls below the specified threshold.
• Provides an adjustable reset timeout period to accommodate different system requirements.
• Offers a power-on reset delay time programmable feature for precise control.

Advantages and Disadvantages

Advantages

• Low-power consumption helps in energy-efficient designs.
• Wide operating voltage range allows compatibility with various systems.
• Small package size enables usage in space-constrained applications.
• High accuracy ensures reliable voltage monitoring.
• Adjustable reset timeout period and programmable power-on reset delay time offer flexibility.

Disadvantages
