Essence

The essence of MIC6315-31D4UY-TR is its ability to ensure proper system operation by monitoring the voltage level and generating a reset signal when necessary.

Packaging/Quantity

MIC6315-31D4UY-TR is typically packaged in reels, with 3000 units per reel.

Specifications

• Supply Voltage Range: 1.0V to 5.5V
• Threshold Voltage: 3.1V
• Reset Timeout Period: Adjustable (typically 140ms)
• Quiescent Current: 10µA (typical)
• Power-On Reset Delay: 20ms (typical)
• Operating Temperature Range: -40°C to +85°C

Pin Configuration

MIC6315-31D4UY-TR has three pins:

1. VCC: Connects to the positive supply voltage.
2. GND: Connects to the ground reference.
3. RESET: Output pin that provides a reset signal when the monitored voltage falls below the threshold.

Functional Features

• Monitors the voltage level and generates a reset signal when the voltage falls below the threshold.
• Adjustable reset timeout period allows customization based on system requirements.
• Low quiescent current ensures minimal power consumption.
• Power-on reset delay provides a stable reset signal during power-up.

Advantages

• Wide supply voltage range allows compatibility with various systems.
• Small package size enables space-saving designs.
• Adjustable reset timeout period offers flexibility in system design.
• Low quiescent current minimizes power consumption.

Disadvantages

• Fixed threshold voltage may not be suitable for all applications.
• Limited number of pins restricts additional functionality integration.

Working Principles

MIC6315-31D4UY-TR operates by continuously monitoring the voltage level at the VCC pin. When the voltage falls below the threshold (3.1V), the RESET pin is pulled low, indicating a reset condition. The reset signal remains active until the voltage rises above the threshold and the reset timeout period elapses.

Detailed Application Field Plans

MIC6315-31D4UY-TR finds applications in various electronic systems where voltage monitoring and reset generation are critical. Some potential application fields include:

1. Microcontrollers and microprocessors
2. Embedded systems
3. Power management circuits
4. Battery-powered devices
5. Industrial control systems
