Detailed Pin Configuration

MIC803-29D3VM3-TR has three pins:

1. VDD: Power supply input pin.
2. GND: Ground reference pin.
3. RESET: Output pin that indicates the status of the monitored voltage.

Functional Features

• Voltage Monitoring: The MIC803-29D3VM3-TR continuously monitors the input voltage and provides a reset signal when it falls below the specified threshold.
• Reset Signal Generation: When the 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 specific duration (reset timeout delay) after the voltage rises above the threshold, allowing the system to stabilize before resuming normal operation.

Advantages and Disadvantages

Advantages

• Low power consumption makes it suitable for battery-powered devices.
• Wide operating voltage range allows compatibility with various systems.
• Small package size enables space-saving designs.
• High accuracy ensures reliable voltage monitoring.

Disadvantages

• The reset timeout delay may not be adjustable, limiting flexibility in certain applications.
• Lack of additional features such as hysteresis or adjustable threshold voltage.

Working Principles

MIC803-29D3VM3-TR operates based on a voltage comparator circuit. It compares the input voltage with the preset threshold voltage. When the input voltage drops below the threshold, the output goes low, indicating the need for a system reset. The reset signal remains active for the specified reset timeout delay after the voltage rises above the threshold.
