Advantages

• Wide operating voltage range allows for versatile applications.
• High accuracy in voltage detection ensures reliable performance.
• Low supply current minimizes power consumption.
• Small package size enables space-saving designs.
• Built-in delay circuit prevents false resets.

Disadvantages

• Limited to voltage detection and reset functions, not suitable for other complex tasks.
• Manual reset pin may require additional external components for proper functionality.

Working Principles

The S-80821CLNB-B6GT2U IC operates by continuously monitoring the voltage level at the VDET pin. When the voltage falls below the detection threshold, the RESET pin is activated, providing a low-level output signal. The built-in delay circuit ensures that the reset signal remains active for a specific duration (200ms) after the voltage returns to the normal range.
