2. GND: Ground connection
3. MR: Manual reset input
4. RESET: Reset output

Functional Features

Voltage Monitoring

ADM802MARN-REEL continuously monitors the input voltage and compares it with the preset threshold voltage. If the voltage drops below the threshold, the reset output is activated.

Reset Signal Generation

When the monitored voltage falls below the threshold, the reset output is asserted, indicating that the device should be reset or powered off.

Manual Reset

The manual reset input (MR) allows for an external reset signal to override the voltage monitoring function and assert the reset output.

Advantages

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

Disadvantages

• Limited options for reset threshold voltage and timeout period may not suit all applications.
• Lack of additional features such as hysteresis or adjustable delay limits its flexibility in certain scenarios.

Working Principles

ADM802MARN-REEL operates by continuously monitoring the input voltage using an internal voltage comparator. When the voltage drops below the preset threshold, the reset output is activated. The manual reset input allows for external control over the reset signal.

Detailed Application Field Plans

ADM802MARN-REEL finds applications in a wide range of electronic devices, including:

1. Microcontrollers and microprocessors
2. Power management systems
3. Industrial automation equipment
4. Consumer electronics
