2. GND: Ground reference pin.
3. RESET: Active low reset output pin.

Functional Features

• Voltage Monitoring: MIC809-5SYC3 continuously monitors the supply voltage and generates a reset signal when it falls below the specified threshold.
• Reset Output: The active low reset output signal is generated to reset the microcontroller or other digital circuitry when the voltage drops below the threshold.
• Reset Timeout: The reset signal remains active for a specific timeout period after the voltage rises above the threshold, ensuring stable operation during power-up.

Advantages and Disadvantages

Advantages

• Low power consumption ensures minimal impact on overall system energy efficiency.
• Wide operating voltage range allows compatibility with various power supply configurations.
• Small package size enables space-saving designs in compact electronic devices.
• High accuracy ensures reliable voltage monitoring and reset functionality.

Disadvantages

• The reset timeout period may not be adjustable, limiting flexibility in certain applications.
• Limited pin configuration options may restrict integration with specific circuit layouts.

Working Principles

MIC809-5SYC3 operates based on a voltage comparator circuit. It compares the supply voltage with the preset threshold voltage. When the supply voltage drops below the threshold, the reset output is activated. Once the supply voltage rises above the threshold and remains stable for the specified timeout period, the reset signal deactivates.
