• MR: Manual reset input (active-low)
• N.C.: No connection (reserved for future use)

Functional Features

• Precision voltage monitoring: The MIC6315-31D4U TR accurately monitors the voltage level of the power supply.
• Reset generation: When the voltage falls below the specified threshold, the IC generates a reset signal to ensure proper system operation.
• Manual reset capability: The MR pin allows for a manual reset input, which can be used to override the monitoring function.

Advantages and Disadvantages

Advantages: - Wide supply voltage range enables compatibility with various systems. - Small package size (DFN-6) saves board space. - Low power consumption. - High accuracy in voltage monitoring.

Disadvantages: - Lack of adjustable reset threshold voltage. - Limited timeout period options.

Working Principles

The MIC6315-31D4U TR operates by continuously monitoring the voltage level at the VCC pin. When the voltage drops below the specified threshold (3.1V), the IC asserts the RESET pin low, indicating a reset condition. This ensures that the connected microcontroller or digital system is properly reset and starts in a known state.

The IC also includes a manual reset feature, where pulling the MR pin low overrides the voltage monitoring function and forces a reset signal regardless of the voltage level.

Detailed Application Field Plans

The MIC6315-31D4U TR finds applications in various electronic systems where reliable voltage monitoring and reset functionality are crucial. Some potential application fields include:

1. Microcontrollers: Ensures proper initialization and operation of microcontroller-based systems.
2. Embedded Systems: Provides reliable reset functionality for embedded systems, preventing erratic behavior during power-up or voltage fluctuations.
3. Industrial Control Systems: Monitors power supply voltage in industrial control systems, ensuring stable and safe operation.
4. Automotive Electronics: Used in automotive applications to monitor and reset critical electronic components, enhancing system reliability.
