• Adjustable reset threshold: The reset threshold voltage can be adjusted according to the specific requirements of the application.
• Active-low push-pull output: The active-low RESET pin provides a push-pull output, allowing for easy integration with other circuitry.
• Low quiescent current: With a low quiescent current of 1.5µA, the MIC6315-31D3U TR minimizes power consumption in battery-powered applications.

Advantages and Disadvantages

Advantages

• Wide operating voltage range allows compatibility with various systems.
• Adjustable reset threshold voltage provides flexibility in different applications.
• Small package size enables space-saving designs.
• Low quiescent current prolongs battery life in portable devices.

Disadvantages

• Limited reset timeout period may not be suitable for certain time-critical applications.
• Lack of built-in hysteresis may result in oscillations near the threshold voltage.

Working Principles

The MIC6315-31D3U TR operates by continuously monitoring the supply voltage. When the voltage falls below the set threshold, the active-low RESET pin is asserted, indicating a voltage fault condition. Once the voltage rises above the threshold, the RESET pin returns to its inactive state. The adjustable reset threshold allows customization based on the specific voltage requirements of the system.
