```

---

| | --| RESET |-- --| GND |-- --| VCC |-- |_______| ```

Pin Description: - RESET: Output pin that generates a reset signal when the monitored voltage falls below the threshold. - GND: Ground reference pin. - VCC: Power supply input pin.

Functional Features

• Voltage Monitoring: ADM1815-10ART-RL7 continuously monitors the power supply voltage and compares it with the preset threshold voltage.
• Reset Generation: When the voltage drops below the threshold, the device generates a reset signal to initiate a system reset.
• Adjustable Timeout Period: The reset signal remains active for a programmable period after the voltage rises above the threshold, allowing sufficient time for the system to stabilize.
• Low Quiescent Current: The IC consumes minimal current during operation, ensuring power efficiency.

Advantages and Disadvantages

Advantages

• Wide operating voltage range allows compatibility with various systems.
• Small package size enables space-saving designs.
• Adjustable timeout period provides flexibility in different applications.
• Low quiescent current minimizes power consumption.

Disadvantages

• Fixed reset threshold voltage may not be suitable for all voltage monitoring requirements.
• Limited pin configuration options may restrict certain system designs.

Working Principles

ADM1815-10ART-RL7 operates by comparing the monitored voltage with the preset threshold voltage. When the voltage falls below the threshold, the internal circuitry triggers the RESET pin, generating a reset signal. This signal remains active for a programmable period after the voltage rises above the threshold, allowing the system to stabilize before resuming normal operation.
