2. GND: Ground pin (-)
3. RESET: Reset output pin

Functional Features

• Voltage Monitoring: MIC803-29D2VC3-TR continuously monitors the voltage level and provides a reset signal when the voltage drops below the specified threshold.
• Reset Output: The reset pin goes low when the voltage falls below the threshold, indicating a system reset condition.
• Reset Timeout: The reset signal remains active for a specific timeout period after the voltage rises above the threshold, allowing the system to stabilize before resuming normal operation.

Advantages and Disadvantages

Advantages

• Low power consumption ensures minimal impact on overall system performance.
• Wide operating voltage range makes it compatible with various electronic devices.
• Small package size allows for space-efficient integration into compact designs.
• High accuracy ensures reliable voltage monitoring and reset functionality.

Disadvantages

• The reset timeout period may not be adjustable, limiting flexibility in certain applications.
• Limited availability of alternative models from other manufacturers.

Working Principles

MIC803-29D2VC3-TR operates by comparing the input voltage with the preset threshold. When the voltage drops below the threshold, the reset output is activated, indicating a system reset condition. The reset signal remains active for the specified timeout period after the voltage rises above the threshold, allowing the system to stabilize before resuming normal operation.
