• Operating temperature range: -40°C to +85°C

Detailed Pin Configuration

ADM1815-20ARTZ-RL7 has three pins:

1. VCC: Connects to the supply voltage.
2. GND: Ground reference.
3. RESET: Output pin that indicates the status of the monitored voltage.

Functional Features

• Under-voltage detection: Monitors the voltage level and generates a reset signal when it falls below the threshold voltage.
• Power-on reset: Generates a reset signal upon power-up to ensure proper initialization of the system.
• Manual reset input: Allows for external triggering of a reset signal.
• Reset output: Provides an indication of the voltage status through an open-drain output.

Advantages and Disadvantages

Advantages

• Wide operating voltage range allows for compatibility with various systems.
• Low power consumption minimizes energy usage.
• High accuracy ensures reliable voltage monitoring.
• Small package size enables space-saving designs.

Disadvantages

• Limited threshold voltage options may not suit all applications.
• Lack of adjustable threshold voltage limits flexibility in certain scenarios.

Working Principles

ADM1815-20ARTZ-RL7 operates by comparing the monitored voltage with the preset threshold voltage. When the voltage falls below the threshold, the reset output is activated, indicating a fault condition. The device continuously monitors the voltage and generates a reset signal until the voltage rises above the threshold again.

Detailed Application Field Plans

ADM1815-20ARTZ-RL7 finds applications in various electronic systems that require reliable voltage supervision. Some common application fields include:

1. Microcontrollers: Ensures proper operation by monitoring the supply voltage.
2. Industrial control systems: Provides voltage supervision to prevent system failures.
3. Battery-powered devices: Protects against undervoltage conditions, extending battery life.
