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

Functional Features

• Voltage Monitoring: MIC803-29D2VM3-TR continuously monitors the supply voltage and generates a reset signal when the voltage drops below the specified threshold.
• Reset Signal Generation: When the supply voltage falls below the threshold, the reset output becomes active low, indicating that the system should be reset.
• 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-saving 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.
• Lack of additional features such as hysteresis or adjustable thresholds may restrict its use in more specialized systems.

Working Principles

MIC803-29D2VM3-TR operates by comparing the supply voltage with the preset threshold. When the voltage drops below the threshold, the internal circuitry triggers the reset output to become active low. This signal remains active for a specific timeout period after the voltage rises above the threshold, providing sufficient time for the system to stabilize before resuming normal operation.

Detailed Application Field Plans

MIC803-29D2VM3-TR finds application in various electronic devices where voltage monitoring and reset functions are critical. Some potential application fields include:

1. Microcontrollers: Ensuring proper functioning and preventing data corruption during power fluctuations.
2. Embedded Systems: Protecting sensitive components from damage caused by unstable power supply.
3. Industrial Automation: Maintaining system integrity and preventing malfunctions due to voltage variations.
4. Automotive Electronics: Safeguarding critical systems and ensuring reliable operation under varying voltage conditions.
