Detailed Pin Configuration

The S-80817CNUA-B8CT2U IC has the following pin configuration:

1. VDD: Supply voltage input
2. GND: Ground reference
3. RESET: Active low reset output

Functional Features

• Voltage monitoring: The IC continuously monitors the supply voltage and compares it with the preset threshold voltage.
• Reset signal generation: When the supply voltage falls below the threshold, the IC generates an active low reset signal.
• Built-in delay: The IC incorporates a delay time of 200ms to ensure stable operation during power-up or voltage fluctuations.

Advantages and Disadvantages

Advantages

• Wide operating voltage range allows for versatile applications.
• Low supply current minimizes power consumption.
• Small package size enables space-saving designs.
• Accurate voltage monitoring ensures reliable system operation.

Disadvantages

• Limited reset threshold voltage options may not suit all application requirements.
• Lack of adjustable delay time may restrict certain timing-sensitive applications.

Working Principles

The S-80817CNUA-B8CT2U IC operates by comparing the supply voltage with the preset threshold voltage. When the supply voltage drops below the threshold, the internal circuitry triggers the generation of an active low reset signal. This signal remains active until the supply voltage rises above the threshold and the built-in delay time elapses.

Detailed Application Field Plans

The S-80817CNUA-B8CT2U IC finds applications in various electronic devices that require voltage monitoring and reset functionality. Some potential application fields include:

1. Microcontrollers and microprocessors: Ensuring proper system initialization and preventing data corruption during power-up or voltage fluctuations.
