Functional Features

Voltage Detection

The S-80954CLMC-G7QT2U can accurately detect voltage levels within the specified range. It provides a reliable indication of the power supply status in electronic devices.

Reset Function

When the detected voltage falls below the preset threshold, the S-80954CLMC-G7QT2U generates a reset signal through its open-drain reset output pin. This ensures that the device is properly reset and prevents any potential malfunctions.

Manual Reset

The MR (Manual Reset) pin allows for an external manual reset function. When this pin is pulled low, it overrides the voltage detection and forces a reset signal.

Advantages and Disadvantages

Advantages

• Wide operating voltage range
• High accuracy in voltage detection
• Low quiescent current consumption
• Compact package size for space-constrained applications
• Manual reset capability for flexibility

Disadvantages

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

Working Principles

The S-80954CLMC-G7QT2U operates based on a voltage divider network connected to the VOUT pin. When the supply voltage exceeds the preset detection threshold, the internal comparator triggers the reset output to a high impedance state. Conversely, when the supply voltage falls below the threshold, the reset output is pulled low, indicating a reset condition.

Detailed Application Field Plans

The S-80954CLMC-G7QT2U finds applications in various electronic devices where accurate voltage detection and reliable 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
