Pin Configuration

The MAX823SEXK+T is a 5-pin device with the following pinout:

  1. GND (Ground)
  2. RESET (Reset Output)
  3. VCC (Supply Voltage)
  4. MR (Manual Reset Input)
  5. TH (Threshold Voltage Selection)

Functional Features

  • Monitors the supply voltage continuously
  • Generates a reset signal when the voltage drops below the selected threshold
  • Provides a manual reset option through the MR pin
  • Low quiescent current for power-sensitive applications
  • Precision voltage monitoring for reliable system operation

Advantages and Disadvantages

Advantages: - Wide supply voltage range allows compatibility with various systems - Multiple threshold voltage options provide flexibility in voltage monitoring - Low quiescent current minimizes power consumption - Small package size enables space-constrained designs

Disadvantages: - Limited number of threshold voltage options available - Manual reset functionality may not be required in all applications

Working Principles

The MAX823SEXK+T is designed to monitor the supply voltage of a system. It compares the voltage level with the selected threshold voltage and generates a reset signal when the voltage falls below this threshold. The device continuously monitors the voltage, ensuring reliable operation of the system.

In addition to the automatic reset function, the MAX823SEXK+T also provides a manual reset option. When a logic low signal is applied to the MR pin, it forces an immediate reset, regardless of the voltage level. This feature allows for manual control over the system reset.

Detailed Application Field Plans

The MAX823SEXK+T is commonly used in various applications where voltage monitoring and system reset functionality are critical. Some typical application fields include:

  1. Battery-Powered Devices: Ensures proper operation by monitoring battery voltage and initiating a reset if the voltage drops below a safe threshold.
  2. Microcontroller Systems: Protects microcontrollers from unstable power conditions by providing a reliable reset signal during power-up or voltage fluctuations.
  3. Industrial Control Systems: Monitors power supply voltages in industrial environments, preventing system malfunctions due to voltage variations.
  4. Automotive Electronics: Safeguards automotive electronic systems by detecting low voltage conditions and triggering a reset to prevent data corruption or system failures.
