2. GND: Ground reference pin.
3. RESET: Output pin that indicates the status of the monitored voltage.

Functional Features

• Voltage Monitoring: MIC803-41D3VC3-TR continuously monitors the input voltage and provides a reset signal when it falls below the threshold voltage.
• Reset Signal Generation: When the input voltage drops below the threshold, the RESET pin goes low, indicating the need for a system reset.
• Reset Timeout: The reset signal remains active for a fixed timeout period (140ms) after the voltage rises above the threshold, ensuring a stable system operation.

Advantages and Disadvantages

Advantages

• Low power consumption helps in energy-efficient designs.
• Wide operating voltage range makes it compatible with various systems.
• Small package size allows for space-saving integration.
• High accuracy ensures reliable voltage monitoring.
