• Reset Timeout Delay: 140ms (typical)
• Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

MIC803-31D4VM3-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 device being monitored.

Functional Features

• Voltage Monitoring: MIC803-31D4VM3-TR continuously monitors the voltage level and generates 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 a reset condition.
• Reset Timeout: The reset signal remains active for a specific duration (reset timeout delay) after the voltage rises above the threshold, ensuring stability before normal operation resumes.

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.
• Limited availability of alternative models from other manufacturers.

Working Principles

MIC803-31D4VM3-TR operates by comparing the input voltage with the preset threshold. When the voltage drops below the threshold, the internal circuitry triggers the generation of a reset signal. This signal remains active for the specified reset timeout delay after the voltage rises above the threshold, ensuring stability before normal operation resumes.

Detailed Application Field Plans

MIC803-31D4VM3-TR finds applications in various electronic devices that require voltage monitoring and reset functions. Some common application fields include:

1. Microcontrollers: Ensuring proper functioning by monitoring supply voltage levels.
2. Embedded Systems: Preventing data corruption or system malfunction due to voltage fluctuations.
3. Power Management: Protecting sensitive components from damage caused by undervoltage conditions.
4. Industrial Automation: Maintaining stable operation of control systems during power supply variations.

Detailed and Complete Alternative Models

While MIC803-31D4VM3-TR is a widely used voltage monitoring IC, there are alternative models available from different manufacturers. Some notable alternatives include:

1. MAX803/MAX809: Manufactured by Maxim Integrated, these ICs offer similar functionality with adjustable reset timeout delays.
2. MCP100: Produced by Microchip Technology, this IC provides additional features such as manual reset input and watchdog timer functionality.

These alternative models can be considered based on specific requirements and design constraints.
