Detailed Pin Configuration

The MAX6313UK38D2-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 supply voltage
  5. TH: Threshold voltage selection pin

Functional Features

  • Monitors the supply voltage and generates a reset signal when it drops below the selected threshold voltage.
  • Provides an active-low reset output that remains low until the supply voltage rises above the threshold voltage for the specified timeout period.
  • Offers manual reset capability through the MR pin.

Advantages and Disadvantages

Advantages

  • Low-power consumption, suitable for battery-powered applications.
  • Precision voltage monitoring ensures reliable system operation.
  • Adjustable threshold voltage allows flexibility in different voltage level requirements.
  • Small package size enables space-saving designs.

Disadvantages

  • Limited threshold voltage options may not cover all possible voltage levels.
  • Reset timeout period options may not be suitable for all applications.

Working Principles

The MAX6313UK38D2-T operates by continuously monitoring the supply voltage connected to the VCC pin. When the voltage falls below the selected threshold voltage, the reset output (RESET) is activated and held low for the specified timeout period. This signal can be used to reset microcontrollers, digital logic circuits, or other system components.

The manual reset input (MR) allows an external signal to force a reset regardless of the monitored voltage level. This feature is useful during system testing or when a manual reset is required.

Detailed Application Field Plans

The MAX6313UK38D2-T is commonly used in various applications where reliable voltage monitoring and reset functionality are essential. Some typical application fields include:

  1. Microcontroller Systems: Ensures proper initialization and reliable operation of microcontrollers by providing a reset signal when the supply voltage drops below a certain threshold.
  2. Power Management: Monitors power supply voltages in battery-powered devices, preventing erratic behavior or data corruption during low voltage conditions.
  3. Industrial Control Systems: Protects sensitive electronic components from voltage fluctuations, ensuring stable and safe operation of industrial control systems.
  4. Automotive Electronics: Provides voltage monitoring and reset capabilities in automotive applications, enhancing system reliability and safety.
