2. VDD (Supply voltage)
3. RESET (Reset output)
4. VDET (Voltage detection input)
5. NC (No connection)

Functional Features

• Voltage detection: The S-80846CNPF-B87TFU can accurately detect the input voltage within the specified range.
• Reset function: When the input voltage falls below the detection threshold, the reset output is activated.
• Delay circuit: A built-in delay circuit ensures that false resets are prevented, providing stable operation.

Advantages and Disadvantages

Advantages

• Wide voltage detection range allows for versatile applications.
• Low supply current minimizes power consumption.
• High accuracy voltage detection threshold ensures reliable operation.
• Small package size enables space-saving designs.
• RoHS compliance promotes environmental friendliness.

Disadvantages

• The open-drain output requires an external pull-up resistor for proper signal level translation.
• Limited pin configuration options may not suit all application requirements.

Working Principles

The S-80846CNPF-B87TFU operates by continuously monitoring the input voltage at the VDET pin. When the voltage falls below the detection threshold, the reset output is activated, indicating a low-voltage condition. The built-in delay circuit prevents false resets caused by temporary voltage fluctuations or noise.

Detailed Application Field Plans

The S-80846CNPF-B87TFU finds applications in various electronic devices that require voltage monitoring and reset functions. Some potential application fields include:

1. Battery-powered devices: Ensures proper shutdown or warning when the battery voltage drops below a certain level.
2. Microcontrollers and microprocessors: Provides a reliable reset signal during power-up or voltage drop events.
3. Industrial control systems: Monitors power supply voltages to prevent malfunctions or damage to sensitive components.
4. Automotive electronics: Protects critical circuits from undervoltage conditions, ensuring safe and reliable operation.

Detailed and Complete Alternative Models

1. S-80846CNNP-B87TFU: Similar to S-80846CNPF-B87TFU, but with active-low reset output.
2. S-80846CNUA-B87TFU: Offers adjustable voltage detection threshold for greater flexibility.
3. S-80846CPNB-B87TFU: Provides a push-pull output instead of an open-drain output.
