Functional Features

• Voltage Monitoring: The MAX6383XR24D3+T continuously monitors the input voltage and compares it with the programmed threshold voltage.
• Reset Generation: When the input voltage falls below the threshold voltage, the IC generates a reset signal to initiate system reset or power-on reset.
• Adjustable Timeout Period: The reset timeout period can be adjusted using external capacitors or set to a fixed value.
• Low Power Consumption: The IC operates with low quiescent current, making it suitable for battery-powered applications.

Advantages and Disadvantages

Advantages: - Compact package size allows for easy integration into space-constrained designs. - Wide range of threshold voltage options provides flexibility for different voltage monitoring requirements. - Adjustable reset timeout period enables customization based on specific system needs. - Low power consumption helps prolong battery life in portable devices.

Disadvantages: - Limited number of available threshold voltage options may not cover all possible voltage monitoring scenarios. - Lack of built-in hysteresis feature may result in potential noise-induced false triggering.

Working Principles

The MAX6383XR24D3+T operates by comparing the input voltage with the programmed threshold voltage. When the input voltage drops below the threshold voltage, the IC triggers the reset signal. The reset signal remains active until the input voltage rises above the threshold voltage and the reset timeout period elapses.
