ADM811SARTZ-REEL7

Product Overview

Category

The ADM811SARTZ-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 ADM811SARTZ-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.
• Small package size: The ADM811SARTZ-REEL7 is available in a small SOT-23 package, which saves board space.

Package and Quantity

The ADM811SARTZ-REEL7 is packaged in a SOT-23 package. It is typically supplied in reels containing a specific quantity of ICs, usually 3000 units per reel.

Specifications

• Supply voltage range: 1.6V to 5.5V
• Reset threshold voltage options: 2.63V, 2.93V, 3.08V, 4.38V
• Quiescent current: 7µA (typical)
• Reset timeout period: 140ms (typical)
• Operating temperature range: -40°C to +85°C

Pin Configuration

The ADM811SARTZ-REEL7 has three pins:

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

Functional Features

• Power-on reset: The ADM811SARTZ-REEL7 generates a reset signal when the supply voltage rises above the threshold, ensuring proper initialization of the system.
• Voltage monitoring: It continuously monitors the supply voltage and asserts the reset signal if it falls below the specified threshold.
• Reset timeout: The reset signal remains asserted for a specific period after the supply voltage rises above the threshold, allowing the system to stabilize before normal operation.

Advantages and Disadvantages

Advantages

• Reliable voltage monitoring and reset functionality.
• Low power consumption, suitable for battery-powered applications.
• Small package size saves board space.

Disadvantages

• Limited reset threshold voltage options.
• Not suitable for high-voltage applications.

Working Principles

The ADM811SARTZ-REEL7 utilizes an internal voltage reference and comparator to monitor the supply voltage. When the voltage drops below the specified threshold, the reset output is asserted. Once the voltage rises above the threshold and remains stable for the reset timeout period, the reset signal is deasserted.

Application Field Plans

The ADM811SARTZ-REEL7 can be used in various electronic devices that require reliable voltage monitoring and reset functions. Some potential application fields include:

1. Microcontrollers: Ensuring proper initialization and reliable operation of microcontroller-based systems.
2. Embedded systems: Providing voltage monitoring and reset capabilities for embedded systems.
3. Industrial control systems: Monitoring the supply voltage in industrial control systems to prevent malfunctions due to voltage fluctuations.
4. Consumer electronics: Incorporating voltage monitoring and reset functionality in consumer electronic devices for enhanced reliability.
