Detailed Pin Configuration

ADM1816-20AKSZ-RL7 has three pins:

1. VCC: Connects to the positive supply voltage.
2. GND: Connects to the ground reference.
3. RESET: Output pin that provides a reset signal when the monitored voltage falls below the threshold.

Functional Features

• Monitors the supply voltage and generates a reset signal when it drops below the specified threshold.
• Provides a stable reset output during power-up and power-down sequences.
• Offers a fixed timeout period to ensure proper system initialization.
• Low quiescent current consumption helps in reducing overall power consumption.

Advantages and Disadvantages

Advantages

• Wide operating voltage range allows compatibility with various electronic systems.
• Accurate voltage monitoring ensures reliable system operation.
• Small package size enables space-saving designs.
