Functional Features

• Voltage detection: The S-80945CLNB-G7FT2U can accurately detect the voltage level at the VIN pin and provide a reset signal when the voltage falls below the specified threshold.
• Reset function: When the detected voltage drops below the threshold, the output pin (OUT) is pulled low, indicating a reset condition.
• Delay circuit: The built-in delay circuit prevents erroneous reset operation due to momentary voltage fluctuations.

Advantages and Disadvantages

Advantages

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

Disadvantages

• Limited reset threshold voltage options may not suit all application requirements.
• Delay time may be longer than desired in certain time-critical applications.

Working Principles

The S-80945CLNB-G7FT2U operates by continuously monitoring the voltage level at the VIN pin. When the voltage falls below the preset threshold, the internal circuit triggers a reset signal, pulling the output pin (OUT) low. This reset signal can be used to initiate appropriate actions in the connected electronic system.
