Pin 1: GND (Ground) Pin 2: VDD (Supply Voltage) Pin 3: VOUT (Reset Output) Pin 4: VDET (Voltage Detection Input) Pin 5: NC (No Connection)

Functional Features

1. Voltage Detection: The S-80922CNPF-G8STFG can accurately detect the input voltage level within the specified range.
2. Reset Function: When the detected voltage falls below the set threshold, the reset output is activated, providing a signal to reset the connected device.
3. Low Power Consumption: With a quiescent current of only 1.0μA, this IC minimizes power consumption in electronic devices.

Advantages and Disadvantages

Advantages

• Wide voltage detection range allows for versatile applications.
• Accurate voltage detection with low tolerance ensures reliable operation.
• Small package size enables space-saving designs.
• Low power consumption prolongs battery life in portable devices.

Disadvantages

• Limited number of available detection voltage options.
• Open drain output requires an external pull-up resistor for certain applications.

Working Principles

The S-80922CNPF-G8STFG operates based on a voltage divider network connected to the VDET pin. When the input voltage exceeds the set threshold, the internal comparator activates the reset output. This signal remains active until the input voltage rises above the threshold again.

Detailed Application Field Plans

The S-80922CNPF-G8STFG finds applications in various electronic devices that require voltage monitoring and reset functionality. Some potential application fields include:

1. Microcontrollers: Ensuring proper reset and initialization during power-up or brownout conditions.
2. Battery-Powered Devices: Preventing damage due to undervoltage conditions and optimizing battery usage.
3. Industrial Control Systems: Providing reliable reset signals for critical control circuits.
4. Automotive Electronics: Monitoring voltage levels in automotive systems to prevent malfunctions.
