2. Reset Function: When the detected voltage falls below the threshold, the product provides an active low reset signal.
3. Built-in Delay Circuit: The integrated delay circuit ensures a stable reset signal for 200ms (typ.) after the voltage returns to the normal range.

Advantages and Disadvantages

Advantages

• Wide voltage detection range allows for versatile applications.
• Low supply current minimizes power consumption.
• Small package size enables space-saving designs.
• Accurate voltage detection with ±2% accuracy.

Disadvantages

• Limited reset threshold voltage options may not suit all applications.
• Active low reset output may require additional circuitry for certain systems.

Working Principles

The S-80849CLMC-B7AT2U operates by comparing 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 built-in delay circuit ensures a stable reset signal for a specific duration, allowing sufficient time for the system to stabilize before resuming operation.
