Detailed Pin Configuration

MIC809LUY-TR has three pins:

1. VDD: Power supply input pin.
2. GND: Ground reference pin.
3. RESET: Active low reset output pin.

Functional Features

• Voltage monitoring: MIC809LUY-TR continuously monitors the supply voltage and generates a reset signal when it falls below the specified threshold.
• Reset generation: The active low reset output signal is triggered when the monitored voltage drops below the threshold, ensuring a controlled system reset.
• Adjustable threshold and timeout: The product offers various options for threshold voltage and reset timeout period, allowing flexibility in different applications.

Advantages and Disadvantages

Advantages

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

Disadvantages

• Limited threshold voltage and reset timeout options may not meet the requirements of all applications.
• Lack of additional features, such as hysteresis control, may limit its use in certain scenarios.

Working Principles

MIC809LUY-TR operates by comparing the supply voltage with the set threshold voltage. When the supply voltage drops below the threshold, the reset output is activated, triggering a system reset. The reset signal remains active until the supply voltage rises above the threshold and the reset timeout period elapses.

Detailed Application Field Plans

MIC809LUY-TR finds applications in various electronic devices where voltage monitoring and controlled reset functions are crucial. Some specific application areas include:

1. Microcontrollers: Ensuring reliable operation by resetting the microcontroller when the supply voltage falls below a safe level.
2. Embedded Systems: Preventing data corruption and ensuring proper functioning by initiating a reset during voltage fluctuations.
3. Power Management: Protecting sensitive components from damage caused by undervoltage conditions.
4. Industrial Control Systems: Maintaining system integrity by resetting critical components during power supply disturbances.
