MAX6412UK18+T

Basic Information Overview

  • Category: Integrated Circuit (IC)
  • Use: Voltage Monitor and Reset Circuit
  • Characteristics: Low-power, low-voltage operation
  • Package: SOT23-5
  • Essence: Monitors voltage levels and provides reset signals to microcontrollers or other digital systems
  • Packaging/Quantity: Tape and Reel, 3000 units per reel

Specifications

  • Supply Voltage Range: 1.6V to 5.5V
  • Threshold Voltage Options: 1.8V, 2.5V, 3.0V, 3.3V, 5.0V
  • Reset Timeout Period: Adjustable from 1ms to 640ms
  • Quiescent Current: 1µA (typical)

Detailed Pin Configuration

The MAX6412UK18+T IC has a total of 5 pins: 1. GND: Ground connection 2. MR: Manual Reset input pin 3. RESET: Active-low Reset output pin 4. VCC: Positive supply voltage input 5. TH: Threshold voltage selection pin

Functional Features

  • Monitors the supply voltage and asserts a reset signal when it falls below the threshold voltage.
  • Provides an adjustable reset timeout period to ensure proper system initialization.
  • Offers a manual reset input for immediate system reset.
  • Low quiescent current consumption makes it suitable for battery-powered applications.

Advantages

  • Wide supply voltage range allows compatibility with various systems.
  • Adjustable reset timeout period offers flexibility in system design.
  • Small package size enables space-saving on PCBs.
  • Low quiescent current minimizes power consumption.

Disadvantages

  • Limited threshold voltage options may not cater to all voltage requirements.
  • Lack of built-in hysteresis may result in false triggering in noisy environments.

Working Principles

The MAX6412UK18+T operates by continuously monitoring the supply voltage through the TH pin. When the voltage falls below the selected threshold voltage, the RESET pin is asserted low, indicating a reset condition. The reset signal remains active until the supply voltage rises above the threshold voltage and the reset timeout period elapses.

Detailed Application Field Plans

  • Microcontroller-based systems requiring reliable power-on reset functionality.
  • Battery-powered devices where low quiescent current consumption is crucial.
  • Embedded systems that need adjustable reset timeout periods for proper initialization.
