Product Overview

Category

ADM708RARZ-REEL 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: ADM708RARZ-REEL is designed to monitor the power supply voltage and provide a reset signal when the voltage falls below a certain threshold.
  • Reset function: It ensures that the microcontroller or other digital circuitry starts operating correctly after power-up or a voltage drop.
  • Low power consumption: The IC operates with low power consumption, making it suitable for battery-powered applications.
  • Wide operating voltage range: ADM708RARZ-REEL can operate within a wide range of input voltages, typically from 1.6V to 5.5V.
  • Small package size: This IC is available in a small package, which makes it suitable for space-constrained designs.

Package and Quantity

ADM708RARZ-REEL is packaged in a small outline integrated circuit (SOIC) package. It is typically sold in reels containing a specific quantity of units, such as 2500 pieces per reel.

Specifications

  • Supply Voltage Range: 1.6V to 5.5V
  • Reset Threshold Voltage: 2.93V (typical)
  • Reset Timeout Period: 140ms (typical)
  • Operating Temperature Range: -40°C to +85°C
  • Package Type: SOIC-8

Pin Configuration

The ADM708RARZ-REEL IC has eight pins arranged in the following configuration:

┌───┬───┐ │ 1 │ 8 │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ 4 │ 5 │ └───┴───┘

Pin Description: 1. VCC: Power supply input 2. GND: Ground 3. MR: Manual reset input 4. RESET: Reset output 5. RESET: Reset output 6. GND: Ground 7. VCC: Power supply input 8. VCC: Power supply input

Functional Features

  • Voltage Monitoring: ADM708RARZ-REEL continuously monitors the power supply voltage and compares it to a preset threshold.
  • Reset Generation: When the voltage falls below the threshold, the IC generates a reset signal to ensure proper operation of the connected circuitry.
  • Manual Reset: The MR pin allows for manual resetting of the device, overriding the automatic reset function.
  • Reset Timeout: After the voltage rises above the threshold, the reset signal remains active for a specific timeout period to allow the system to stabilize.

Advantages and Disadvantages

Advantages

  • Reliable voltage monitoring and reset functionality
  • Low power consumption
  • Wide operating voltage range
  • Small package size for space-constrained designs

Disadvantages

  • Limited number of reset outputs (two in this case)
  • Lack of adjustable reset threshold voltage

Working Principles

ADM708RARZ-REEL operates based on a voltage comparator circuit. It compares the power supply voltage with a preset threshold voltage. When the voltage drops below the threshold, the IC triggers a reset signal. This signal remains active for a specific timeout period after the voltage rises above the threshold. The IC also provides a manual reset option through the MR pin.
