ADM810LARTZ-REEL7

Product Overview

Category

The ADM810LARTZ-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 ADM810LARTZ-REEL7 is designed to monitor the power supply voltage and provide a reset signal when it falls below a specified threshold.
  • Reset function: It ensures that the microcontroller or other digital circuitry is properly reset when the power supply voltage drops below the desired level.
  • Low power consumption: The device operates with low quiescent current, making it suitable for battery-powered applications.
  • Wide operating voltage range: The ADM810LARTZ-REEL7 can operate within a wide voltage range, typically from 1.6V to 5.5V.
  • Small package size: This IC is available in a small SOT-23 package, which is ideal for space-constrained designs.

Package and Quantity

The ADM810LARTZ-REEL7 is packaged in a tape and reel format, containing 3000 units per reel.

Specifications

  • Supply Voltage Range: 1.6V to 5.5V
  • Threshold Voltage Options: 2.93V, 3.08V, 3.15V, 4.38V, 4.63V, 4.75V
  • Quiescent Current: 10µA (typical)
  • Reset Timeout Period: 140ms (typical)
  • Operating Temperature Range: -40°C to +85°C

Pin Configuration

The ADM810LARTZ-REEL7 has three pins:

  1. VCC: Power supply input pin.
  2. GND: Ground reference pin.
  3. RESET: Output pin for the reset signal.

Functional Features

  • Voltage Monitoring: The ADM810LARTZ-REEL7 continuously monitors the VCC voltage and compares it to the preset threshold voltage.
  • Reset Signal Generation: When the VCC voltage falls below the threshold, the device generates a reset signal on the RESET pin, ensuring proper system initialization.
  • Reset Timeout: The reset signal remains active for a fixed period (140ms typical) after the VCC voltage rises above the threshold, allowing sufficient time for stable power supply recovery.

Advantages and Disadvantages

Advantages

  • Reliable Power Supply Monitoring: The ADM810LARTZ-REEL7 ensures that the system is reset when the power supply voltage drops below the specified threshold, preventing erratic behavior.
  • Low Power Consumption: With its low quiescent current, this IC minimizes power consumption in battery-operated devices.
  • Small Package Size: The SOT-23 package enables space-saving designs.

Disadvantages

  • Limited Threshold Voltage Options: The ADM810LARTZ-REEL7 offers a limited range of threshold voltage options, which may not cater to all specific requirements.

Working Principles

The ADM810LARTZ-REEL7 operates by comparing the VCC voltage with the preset threshold voltage. When the VCC voltage drops below the threshold, the reset signal is activated. Once the VCC voltage rises above the threshold, the reset signal remains active for a fixed timeout period, allowing the system to stabilize before normal operation resumes.

Application Field Plans

The ADM810LARTZ-REEL7 finds applications in various electronic devices where reliable voltage monitoring and reset functionality are crucial. Some potential application fields include:

  1. Microcontrollers: Ensuring proper initialization and reliable operation of microcontroller-based systems.
