Functional Features

• Voltage detection: The S-80940CLPF-G7ATFU can accurately detect the input voltage within the specified range.
• Reset function: When the detected voltage falls below the threshold, the reset output becomes active low, indicating a reset condition.
• Low power consumption: With a quiescent current of only 1.0µA, this IC minimizes power consumption in battery-powered applications.

Advantages and Disadvantages

Advantages

• Wide voltage detection range allows for versatile use in various electronic devices.
• Low supply current ensures minimal power consumption.
• Small package size (SOT-23-5) enables space-saving designs.

Disadvantages

• The reset output is active low, which may not be suitable for all applications requiring a different reset polarity.
• Limited output current capability (10mA max.) may restrict usage in high-current applications.

Working Principles

The S-80940CLPF-G7ATFU operates based on a voltage divider network connected to the VDD pin. When the input voltage falls below the detection threshold, the internal comparator triggers the reset function, pulling the RESET pin low. This indicates a reset condition until the input voltage rises above the threshold again.
