3. RESET: Output signal indicating the status of the monitored voltage

Functional Features

• Accurate voltage monitoring: The MIC6315-40D4UY-TR continuously monitors the power supply voltage and provides a reset signal when it falls below the programmed threshold.
• Adjustable reset threshold: The reset threshold voltage can be adjusted using external resistors, allowing flexibility in different applications.
• Low quiescent current consumption: The device consumes minimal current during operation, ensuring efficient power usage.
• Power-on reset delay: The MIC6315-40D4UY-TR incorporates a 100ms delay to ensure stable power supply before releasing the reset signal.

Advantages and Disadvantages

Advantages

• Wide voltage monitoring range allows compatibility with various electronic systems.
• Adjustable reset threshold provides flexibility in different applications.
• Low quiescent current consumption minimizes power wastage.
• Small package size enables space-saving designs.
• Wide operating temperature range ensures reliable performance in diverse environments.

Disadvantages

• Lack of built-in hysteresis may lead to potential false triggering in noisy environments.
• Limited number of pins restricts additional functionalities without external circuitry.

Working Principles

MIC6315-40D4UY-TR operates by continuously comparing the monitored voltage (VDD) with the programmed threshold voltage. When VDD falls below the threshold, the reset output is activated, indicating a power failure or an out-of-range condition. The reset signal remains active until VDD rises above the threshold voltage and stabilizes for the specified power-on reset delay time.
