Detailed Pin Configuration

The MAX824TEUK+T has a total of five pins:

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

Functional Features

  • Monitors the voltage level of the power supply continuously
  • Provides a reset signal when the voltage falls below the set threshold
  • Offers an adjustable or fixed reset timeout period
  • Allows manual reset capability through the MR pin
  • Provides multiple threshold voltage options for flexibility

Advantages and Disadvantages

Advantages

  • Low-power consumption, suitable for battery-powered applications
  • Precision voltage monitoring ensures reliable system operation
  • Small package size allows for space-constrained designs
  • Wide operating temperature range enables usage in various environments

Disadvantages

  • Limited threshold voltage options may not cater to all specific requirements
  • Lack of built-in hysteresis may result in potential noise-related issues

Working Principles

The MAX824TEUK+T operates by comparing the supply voltage with the set threshold voltage. When the supply voltage drops below the threshold, the reset output is activated, indicating a power failure or low voltage condition. The reset signal remains active until the supply voltage rises above the threshold or a manual reset is triggered through the MR pin.

Detailed Application Field Plans

The MAX824TEUK+T finds applications in various fields, including:

  1. Microcontroller-based systems: Provides reliable power-on reset functionality for microcontrollers, ensuring proper initialization.
  2. Battery-powered devices: Monitors battery voltage and triggers a reset when the battery level becomes critically low.
  3. Industrial automation: Ensures safe operation by monitoring power supply integrity and initiating system resets if necessary.
  4. Automotive electronics: Protects sensitive electronic components from voltage fluctuations and provides reset signals when needed.

Detailed and Complete Alternative Models

  1. MAX823TEUK+T: Similar to MAX824TEUK+T but with fixed threshold voltage options of 2.5V and 3.0V.
  2. MAX825TEUK+T: Offers adjustable reset timeout period in addition to voltage monitoring capabilities.
  3. MAX826TEUK+T: Provides additional hysteresis for improved noise immunity.
