Functional Features

• Voltage Monitoring: The MIC6315-46D4U TR continuously monitors the supply voltage and provides a reset signal when it falls below the specified threshold.
• Power-On Reset: It includes a power-on reset delay circuit that ensures a stable reset signal is generated during power-up.
• Low Quiescent Current: The device consumes very low current, making it suitable for battery-powered applications.
• Push-Pull Output: The reset output is in an active-low push-pull configuration, providing a strong and reliable signal.

Advantages and Disadvantages

Advantages

• Wide voltage range allows compatibility with various electronic circuits.
• Precision voltage threshold ensures accurate monitoring.
• Low quiescent current minimizes power consumption.
• Small package size enables space-saving designs.

Disadvantages

• Limited to applications requiring a supply voltage below 5.5V.
• Active-low push-pull output may not be suitable for all circuit configurations.

Working Principles

The MIC6315-46D4U TR operates by comparing the supply voltage with a preset threshold. When the voltage drops below the threshold, the reset output is activated, indicating a power failure or unstable voltage condition. The power-on reset delay circuit ensures that the reset signal remains active for a specific duration during power-up, allowing the system to stabilize before normal operation resumes.
