Functional Features

Voltage Detection

S-80824KNUA-D2BT2G is designed to accurately detect the input voltage level within the specified range. It compares the input voltage with the internally set detection voltage and generates a reset signal when the voltage falls below the detection threshold.

Reset Output

When the input voltage drops below the detection threshold, the RESET pin goes low, indicating a reset condition. This signal can be used to trigger various actions, such as restarting the microcontroller or resetting other circuitry.

Built-in Delay Circuit

To prevent false resets caused by momentary voltage fluctuations, the S-80824KNUA-D2BT2G incorporates a built-in delay circuit. This delay ensures that the reset signal is stable for a specified duration (typically 200ms) before returning to its normal state.

Advantages and Disadvantages

Advantages

• Wide voltage detection range allows compatibility with various electronic devices.
• High accuracy ensures reliable voltage detection.
• Low supply current minimizes power consumption.
• Compact package size enables easy integration into space-constrained designs.
• Built-in delay circuit prevents false resets.

Disadvantages

• Limited number of available detection voltage options.
• No adjustable detection voltage setting.

Working Principles

The S-80824KNUA-D2BT2G operates based on a voltage divider network and a comparator. The input voltage is divided by resistors connected to the VIN pin, and the resulting voltage is compared with the internally set detection voltage. When the input voltage falls below the detection threshold, the comparator triggers the reset output, indicating a low voltage condition.
