• Sensitive to noise and voltage spikes, requiring additional protection circuitry in noisy environments.

Working Principles

MIC809JUY-TR operates based on a voltage comparator circuit. It compares the input voltage with the preset threshold voltage. When the input voltage falls below the threshold, the reset output is activated, indicating a low-voltage condition. The hysteresis feature prevents false triggering by introducing a small voltage difference between the rising and falling thresholds.
