Pin 1: VDD (Supply voltage) Pin 2: GND (Ground) Pin 3: RESET (Reset output) Pin 4: VIN (Voltage input) Pin 5: VOUT (Voltage output)

Functional Features

1. Voltage Detection: The S-80946CLNB-G7GT2G can accurately detect voltage levels within the specified range.
2. Reset Function: When the detected voltage falls below the threshold, the IC provides a reset signal to the connected device.
3. Built-in Delay Circuit: The IC includes a delay circuit to prevent false resets caused by momentary voltage fluctuations.

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.
• High accuracy voltage detection ensures reliable operation.

Disadvantages

• Limited reset threshold voltage options may not suit all applications.
• The delay time of 200ms may not be suitable for certain time-critical systems.

Working Principles

The S-80946CLNB-G7GT2G operates based on a voltage divider network connected to the VIN pin. When the input voltage crosses the preset threshold, the internal comparator triggers the RESET pin to provide a low-level reset signal. The built-in delay circuit prevents false resets caused by temporary voltage fluctuations.

Detailed Application Field Plans

The S-80946CLNB-G7GT2G finds applications in various electronic devices that require voltage monitoring and reset functionality. Some potential application fields include:

1. Microcontrollers: Ensuring proper system initialization and preventing data corruption during power-up or brownout conditions.
2. Battery-Powered Devices: Monitoring battery voltage to trigger low-battery warnings or initiate shutdown procedures.
3. Industrial Control Systems: Providing reliable reset signals to ensure safe operation and prevent system malfunctions.
4. Automotive Electronics: Monitoring vehicle battery voltage and triggering appropriate actions in case of abnormal voltage levels.
