Product Overview

Category

The ADM811LART-REEL7 belongs to the category of integrated circuits (ICs).

Use

This product is commonly used in electronic devices for voltage monitoring and reset functions.

Characteristics

• Voltage monitoring: The ADM811LART-REEL7 is designed to monitor the supply voltage of a system and provide a reset signal when the voltage falls below a certain threshold.
• Reset function: It ensures that the system is properly initialized after power-up or when the supply voltage drops below the specified level.
• Low power consumption: This IC has low quiescent current, making it suitable for battery-powered applications.
• Wide operating voltage range: The ADM811LART-REEL7 can operate within a wide voltage range, typically from 1.6V to 5.5V.
• Small package size: It is available in a small SOT-23 package, which is ideal for space-constrained designs.

Detailed Pin Configuration

The ADM811LART-REEL7 has three pins:

1. VCC: This pin is connected to the positive supply voltage.
2. GND: This pin is connected to the ground reference.
3. RESET: This pin outputs a reset signal when the supply voltage falls below the specified threshold.

Functional Features

• Voltage Monitoring: The ADM811LART-REEL7 continuously monitors the supply voltage and compares it to the preset threshold voltage.
• Reset Generation: When the supply voltage drops below the threshold, the RESET pin is asserted, generating a reset signal.
• Hysteresis: The IC incorporates hysteresis to prevent oscillation of the reset signal when the voltage is near the threshold level.
• Power-On Reset: The ADM811LART-REEL7 ensures that the system is properly initialized after power-up by providing a reset signal.

Advantages and Disadvantages

Advantages

• Reliable voltage monitoring and reset functionality.
• Low power consumption, suitable for battery-powered applications.
• Wide operating voltage range allows compatibility with various systems.
• Small package size enables space-saving designs.

Disadvantages

• Limited number of available threshold voltage options.
• Lack of additional features such as adjustable delay or watchdog timer.

Working Principles

The ADM811LART-REEL7 operates based on a voltage comparator circuit. It continuously compares the supply voltage with the preset threshold voltage. When the supply voltage drops below the threshold, the comparator triggers the generation of a reset signal. This signal remains active until the supply voltage rises above the threshold level again.

Detailed Application Field Plans

The ADM811LART-REEL7 finds applications in various electronic devices where reliable voltage monitoring and reset functions are required. Some common application fields include:

1. Microcontrollers: Ensuring proper initialization and reliable operation of microcontroller-based systems.
2. Embedded Systems: Providing voltage monitoring and reset functionality in embedded systems.
3. Industrial Control Systems: Preventing erratic behavior and ensuring stable operation of industrial control systems.
4. Consumer Electronics: Incorporating voltage monitoring and reset features in consumer electronic devices for enhanced reliability.
