2. GND: Ground reference
3. RESET: Reset output
4. VIN: Voltage detection input
5. NC: No connection (unused pin)

Functional Features

• Voltage detection: The IC monitors the voltage level at the VIN pin and compares it with the preset detection voltage. When the voltage falls below the detection threshold, the RESET output is activated.
• Reset signal generation: The RESET output provides a low-level signal to reset the connected device or trigger an appropriate action.
• Open drain output: The N-channel open drain configuration allows for flexibility in connecting external components.

Advantages and Disadvantages

Advantages

• Wide voltage detection range enables compatibility with various applications.
• Low quiescent current minimizes power consumption.
• Compact package size facilitates integration into space-constrained designs.
• Accurate voltage detection ensures reliable operation of electronic devices.

Disadvantages

• Limited output current may not be suitable for high-power applications.
• Single-channel detection limits simultaneous monitoring of multiple voltage levels.

Working Principles

The S-80931CNPF-G81TFG operates based on a voltage divider network connected to the VIN pin. The internal comparator compares the divided voltage with the preset detection voltage. When the input voltage drops below the detection threshold, the comparator triggers the RESET output, providing a low-level signal.
