2. GND: Ground reference
3. RESET: Active low reset output
4. MR: Manual reset input (optional)
5. NC: No connection

Functional Features

• Voltage detection: The IC monitors the supply voltage and provides a reset signal when it falls below the specified threshold.
• Active low reset output: The reset output becomes active (low) when the supply voltage drops below the threshold.
• Manual reset option: The IC can be manually reset by applying a low-level signal to the MR pin.

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.
• Accurate voltage detection ensures reliable operation.

Disadvantages

• Limited number of available threshold voltage options.
• Lack of adjustable hysteresis settings.

Working Principles

The S-80847CNPF-B88TFG IC operates based on a voltage divider network connected to the VDD pin. When the supply voltage drops below the preset threshold, the internal comparator triggers the reset output to become active low. The reset output remains active until the supply voltage rises above the threshold again.

Detailed Application Field Plans

The S-80847CNPF-B88TFG IC finds applications in various electronic devices that require voltage monitoring and reset functions. Some potential application fields include:

1. Microcontrollers: Ensuring proper initialization and safe operation by monitoring the supply voltage.
2. Battery-powered devices: Preventing damage or data loss due to low battery voltage.
3. Industrial control systems: Providing reliable reset signals for critical processes.
4. Automotive electronics: Monitoring vehicle battery voltage and triggering appropriate actions.
