Functional Features

Voltage Detection

S-80850CLMC-B7BT2U is designed to accurately detect the voltage level applied at the VIN pin. It compares this voltage with the preset detection voltage and generates a reset signal when the detected voltage falls below the specified threshold.

Reset Signal Generation

When the voltage at the VIN pin drops below the detection voltage, the RESET pin outputs a low-level signal, indicating the need for a system reset. This feature ensures proper operation and prevents malfunctions caused by insufficient power supply voltage.

Advantages and Disadvantages

Advantages

• Wide voltage detection range allows compatibility with various electronic devices.
• High accuracy ensures reliable voltage detection.
• Low quiescent current minimizes power consumption.
• Small package size enables easy integration into compact designs.
• Built-in delay circuit prevents false reset signals due to temporary voltage fluctuations.

Disadvantages

• Limited number of available detection voltage options.
• N-channel open drain output may require additional components for certain applications.

Working Principles

The S-80850CLMC-B7BT2U operates based on a voltage comparator principle. It compares the voltage at the VIN pin with the preset detection voltage. When the detected voltage falls below the threshold, the internal circuitry triggers the RESET pin to generate a reset signal.
