2. GND: Ground reference
3. RESET: Active-low push-pull reset output

Functional Features

• Voltage Monitoring: ADM1815-5ART-REEL7 continuously monitors the supply voltage and generates a reset signal when the voltage falls below the specified threshold.
• Adjustable Timeout Period: The reset timeout period can be adjusted according to the application requirements, allowing flexibility in system reset timing.
• Push-Pull Output: The reset output is in the form of an active-low push-pull signal, which can be easily interfaced with other digital components.
• Low Power Consumption: This voltage supervisor operates with low quiescent current, ensuring minimal power consumption.

Advantages and Disadvantages

Advantages

• Wide operating voltage range allows compatibility with various electronic systems.
• Adjustable reset timeout period provides flexibility in system reset timing.
• Small package size enables space-saving integration into compact designs.
• Low power consumption ensures energy efficiency.

Disadvantages

• Limited reset threshold voltage options may not cater to all voltage monitoring requirements.
• Lack of additional features such as hysteresis or watchdog functionality.

Working Principles

ADM1815-5ART-REEL7 works based on a voltage comparator circuit that continuously compares the supply voltage with a preset threshold. When the voltage drops below the threshold, the reset output is activated, indicating a power failure or abnormal voltage condition. The reset remains active until the voltage rises above the threshold or the adjustable timeout period elapses.
