MAX825LEUK+T

Product Overview

  • Category: Integrated Circuit (IC)
  • Use: Voltage Supervisor
  • Characteristics: Low-power, Precision, Reset Output
  • Package: SOT-23-5
  • Essence: Monitors the power supply voltage and generates a reset signal when the voltage falls below a predetermined threshold.
  • Packaging/Quantity: Tape and Reel, 3000 units per reel

Specifications

  • Supply Voltage Range: 1.2V to 5.5V
  • Threshold Voltage Options: 2.5V, 3.0V, 3.3V, 3.6V
  • Reset Timeout Period: Adjustable or Fixed (140ms, 280ms, 560ms, 1120ms)
  • Operating Temperature Range: -40°C to +85°C

Pin Configuration

The MAX825LEUK+T has a total of 5 pins:

  1. GND: Ground connection
  2. RESET: Active-low reset output
  3. MR: Manual reset input
  4. VCC: Positive power supply input
  5. TH: Threshold voltage selection pin

Functional Features

  • Monitors the power supply voltage continuously
  • Generates a reset signal when the voltage drops below the set threshold
  • Provides an active-low reset output
  • Offers manual reset capability through the MR pin
  • Low quiescent current consumption for power efficiency

Advantages and Disadvantages

Advantages: - Wide supply voltage range allows compatibility with various systems - Adjustable/reset timeout period provides flexibility in different applications - Low-power consumption extends battery life in portable devices - Small package size enables space-saving designs

Disadvantages: - Limited threshold voltage options may not suit all voltage monitoring requirements - Lack of additional features such as hysteresis adjustment

Working Principles

The MAX825LEUK+T operates by comparing the power supply voltage with the selected threshold voltage. When the supply voltage falls below the threshold, the reset output is activated, indicating a power failure or an out-of-specification condition. The reset remains active until the supply voltage rises above the threshold and the reset timeout period elapses.

Detailed Application Field Plans

The MAX825LEUK+T finds applications in various fields, including:

  1. Microcontrollers and Processors: Ensures reliable system startup and prevents erratic behavior during power fluctuations.
  2. Industrial Control Systems: Monitors power supply integrity to prevent data corruption or equipment damage.
  3. Automotive Electronics: Provides voltage supervision for critical systems, enhancing safety and reliability.
  4. Battery-Powered Devices: Protects against undervoltage conditions, preventing premature shutdown and data loss.
  5. Home Automation: Enables proper functioning of smart home devices by monitoring power supply stability.
