Functional Features

Voltage Detection

S-80815CNNB-B8AT2U can accurately detect voltage levels within the specified range. It provides a reset signal when the detected voltage falls below the set threshold, ensuring proper device operation.

Reset Output

The product features an open-drain output, which allows for flexibility in connecting external components and systems. The reset output becomes active low when the voltage drops below the detection threshold.

Built-in Delay Circuit

To prevent false resets caused by momentary voltage fluctuations, S-80815CNNB-B8AT2U incorporates a built-in delay circuit. This delay ensures that the reset signal remains active for a specific period (200ms typ.) after the voltage returns to the normal range.

Advantages and Disadvantages

Advantages

• Wide voltage detection range
• High accuracy
• Low supply current consumption
• Compact package size
• Built-in delay circuit for stable operation

Disadvantages

• Limited number of available detection voltage options
• Open-drain output requires additional components for certain applications

Working Principles

S-80815CNNB-B8AT2U operates based on a voltage divider network connected to the DET pin. When the input voltage exceeds the detection threshold, the internal comparator triggers the reset output to become inactive. Conversely, when the voltage drops below the threshold, the reset output becomes active, signaling a reset condition.

Detailed Application Field Plans

S-80815CNNB-B8AT2U finds applications in various electronic devices where voltage monitoring and reset functionality are crucial. Some potential application fields include:

1. Microcontrollers and microprocessors
2. Power management systems
3. Battery-powered devices
4. Industrial automation equipment
5. Consumer electronics
