Pin Configuration

ADM1817-20ARTZ-RL has three pins:

1. VDD: Power supply input pin.
2. GND: Ground reference pin.
3. RESET: Output pin for the reset signal.

Functional Features

• Voltage Monitoring: ADM1817-20ARTZ-RL continuously monitors the supply voltage and compares it to the preset threshold voltage.
• Reset Signal Generation: When the supply voltage falls below the threshold, the device generates a reset signal on the RESET pin.
• Reset Timeout: The reset signal remains active for a specific timeout period after the voltage rises above the threshold, ensuring a stable system startup.

Advantages and Disadvantages

Advantages

• Reliable Voltage Monitoring: ADM1817-20ARTZ-RL provides accurate voltage monitoring, preventing erratic behavior of digital circuits due to insufficient power supply.
• Easy Integration: The small package size and low power consumption make it easy to integrate into various electronic designs.
• Wide Operating Voltage Range: The product can be used with different power supply voltages, enhancing its versatility.

Disadvantages

• Lack of Adjustable Threshold: The threshold voltage is fixed at 2.0V, limiting customization options for specific applications.
• Single Reset Timeout Period: The reset timeout period is not adjustable, which may not suit all system requirements.

Working Principles

ADM1817-20ARTZ-RL utilizes an internal voltage reference and comparator to monitor the supply voltage. When the voltage drops below the preset threshold, the comparator triggers the generation of a reset signal. This signal remains active for the specified timeout period after the voltage rises above the threshold, ensuring a stable system startup.
