Pin Configuration

The MAX825MEUK+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 a manual reset option through the MR pin
  • Low-power consumption for energy-efficient applications
  • Precision voltage monitoring for accurate reset generation

Advantages and Disadvantages

Advantages: - Wide supply voltage range allows for versatile applications - Multiple reset threshold and timeout options for flexibility - Small package size enables space-saving designs - Low-power operation extends battery life in portable devices

Disadvantages: - Limited number of available threshold voltage and timeout period combinations - Requires an external pull-up resistor for proper operation

Working Principles

The MAX825MEUK+T operates by monitoring the power supply voltage using an internal voltage reference and comparator. When the voltage falls below the set threshold, the reset output is activated, indicating a power failure or unstable voltage condition. The reset signal remains active until the voltage rises above the threshold or a manual reset is triggered through the MR pin.

Detailed Application Field Plans

The MAX825MEUK+T finds applications in various fields, including:

  1. Microcontrollers: Provides reliable power-on reset functionality to ensure proper initialization of microcontroller-based systems.
  2. Embedded Systems: Monitors power supply voltage in embedded systems to prevent data corruption or erratic behavior during voltage fluctuations.
  3. Industrial Control Systems: Ensures stable operation of industrial control systems by generating a reset signal when the power supply voltage drops below a safe level.
  4. Automotive Electronics: Protects automotive electronic components from voltage dips or transients, preventing system malfunctions or damage.
  5. Battery-Powered Devices: Maximizes battery life in portable devices by initiating a reset when the battery voltage reaches a critical level.
