| | --| |-- |____| ```

Pin Configuration: 1. VDD: Supply voltage input 2. GND: Ground reference 3. RESET: Reset output 4. VOUT: Voltage detection output 5. VIN: Voltage detection threshold setting

Functional Features

• Voltage detection: The S-80918CNMC-G8NT2U can accurately detect the input voltage within the specified range.
• Reset function: It provides a reset signal when the detected voltage falls below the set threshold, ensuring proper operation of the connected device.
• Low power consumption: With a quiescent current of only 0.7µA, it minimizes power consumption in battery-powered applications.
• Open drain output: The reset output is an N-channel open drain, allowing flexibility in connecting to different systems.

Advantages and Disadvantages

Advantages

• Wide operating voltage range
• High accuracy voltage detection
• Low power consumption
• Compact package size
• RoHS compliant

Disadvantages

• Limited number of available detection voltage options
• Requires external components for voltage threshold setting

Working Principles

The S-80918CNMC-G8NT2U operates based on a voltage divider network connected to the VIN pin. When the input voltage exceeds the set threshold, the internal comparator triggers the reset output to go low. This indicates a voltage drop below the desired level, prompting a system reset or other necessary actions.

Detailed Application Field Plans

The S-80918CNMC-G8NT2U finds application in various electronic devices that require accurate voltage detection and reset functionality. Some potential fields of application include:

1. Battery-powered devices: Ensures proper operation and prevents damage due to undervoltage conditions.
2. Microcontrollers and microprocessors: Provides a reliable reset signal during power-up or voltage fluctuations.
3. Industrial control systems: Monitors supply voltages to ensure stable operation of critical components.
4. Automotive electronics: Protects sensitive circuits from voltage variations and initiates system resets when necessary.
