• Offers a manual reset input for immediate system reset.
• Provides a reset output that remains low until the supply voltage rises above the threshold.
• Low quiescent current ensures minimal power consumption.

Advantages and Disadvantages

Advantages: - Wide supply voltage range allows compatibility with various systems. - Multiple threshold voltage options provide flexibility for different applications. - Low quiescent current minimizes power consumption. - Small package size (SOT23-5) enables space-saving designs.

Disadvantages: - Limited to voltage monitoring and reset functionality, not suitable for complex power management tasks. - Requires an external resistor to set the threshold voltage.

Working Principles

The MAX6864UK20D4S+T operates by continuously monitoring the supply voltage. When the voltage falls below the selected threshold, the reset output is activated, indicating a low-voltage condition. The reset output remains low until the supply voltage rises above the threshold, ensuring a reliable power supply. The manual reset input allows for immediate system reset when required.
