Pin 1: VDD (Supply voltage) Pin 2: GND (Ground) Pin 3: RESET (Reset output) Pin 4: DET (Voltage detection input) Pin 5: NC (No connection)

Functional Features

1. Voltage Detection: The S-80821CNPF-B8GTFU accurately detects the voltage level applied to the DET pin within the specified range.
2. Reset Signal Generation: When the detected voltage falls below the threshold, the RESET pin outputs an active low signal, indicating the need for a system reset.
3. Low Power Consumption: With a quiescent current of only 1.0μA, this IC minimizes power consumption and extends battery life in portable devices.
4. Wide Operating Temperature Range: The S-80821CNPF-B8GTFU can operate reliably in a wide temperature range from -40°C to +85°C.

Advantages and Disadvantages

Advantages

• Accurate voltage detection within a wide range
• Low power consumption
• Compact package size for easy integration
• Wide operating temperature range

Disadvantages

• Limited output current capacity (10mA max.)

Working Principles

The S-80821CNPF-B8GTFU operates based on a voltage divider network connected to the DET pin. When the applied voltage exceeds the selected detection threshold, the internal comparator triggers the RESET pin to output an active low signal. This signal can be used to initiate a system reset or perform other necessary actions.

Detailed Application Field Plans

The S-80821CNPF-B8GTFU finds applications in various electronic devices where accurate voltage detection and reset functions are required. Some potential application fields include:
