Functional Features

1. Voltage Detection: The S-80843CNY-B-G can accurately detect the input voltage level within the specified range.
2. Reset Function: When the detected voltage falls below the threshold, the IC generates a reset signal on the output pin.
3. Built-in Delay Circuit: The IC includes a delay circuit that ensures a stable output signal for a specified duration (200ms typ.) after the voltage rises above the threshold.

Advantages and Disadvantages

Advantages

• Wide voltage detection range allows for versatile applications.
• Low quiescent current minimizes power consumption.
• Small package size enables space-saving designs.
• Built-in delay circuit prevents false triggering of reset signals.

Disadvantages

• Limited options for reset threshold voltage selection.
• Requires an external enable signal (ENB) for operation.

Working Principles

The S-80843CNY-B-G operates based on a voltage divider network connected to the VIN pin. The internal comparator compares the divided voltage with the preset threshold voltage. When the input voltage drops below the threshold, the output pin (RESET) is pulled low, indicating a reset condition. The built-in delay circuit ensures a stable output signal for a specified duration after the voltage rises above the threshold.

Detailed Application Field Plans

The S-80843CNY-B-G IC finds applications in various electronic devices where voltage monitoring and reset functions are required. Some potential application fields include:

1. Microcontrollers: Ensuring proper reset functionality during power-up or brownout conditions.
2. Battery-Powered Devices: Detecting low battery voltage and triggering appropriate actions.
3. Power Management Systems: Monitoring supply voltages and initiating system shutdown or protection mechanisms.
4. Industrial Control Systems: Providing voltage supervision and reset capabilities for critical control circuits.
