It is available in various packages to provide optimum integration and protects the system from over-voltage, under-voltage, output overload and overtemperature conditions.

Application Field

The XC6123A345MR-G is especially suitable for use in low voltage system applications such as notebook/personal computers, personal digital assistants (PDAs), digital cameras, LCD displays, LED lighting, power banks and other portable battery-driven applications.

Features & Benefits

The XC6123A345MR-G is equipped with a variety of features to provide the necessary protection and stability needed in low-voltage system applications. These features include high input voltage detection, low voltage detection, output current limit, overtemperature protection, short circuit protection and overcurrent protection.

• High input voltage detection: XC6123A345MR-G offers a wide range of input voltage detection with a maximum voltage of 36V, which allows efficient and reliable operation in low voltage system applications.
• Low voltage detection: The XC6123A345MR-G has an integrated low voltage detection function, which allows for efficient operation when the input voltage drops below a certain threshold.
• Output current limit: By monitoring the output current of the system, the XC6123A345MR-G can prevent excessive loads from creating potential damage. It also ensures a smooth startup of the system.
• Overtemperature protection: This feature ensures the safe operation of the system in the event of abnormally high temperatures, protecting it from potential damage.
• Short circuit protection: The XC6123A345MR-G is designed to prevent any potential damage that can be caused by a short circuit.
• Overcurrent protection: The XC6123A345MR-G has an integrated protection function for overcurrent events, which helps protect the system from harm.

Working Principle

The XC6123A345MR-G works by monitoring the input voltage of a system and ensuring that it is below a certain threshold. When the voltage drops below the threshold, the supervisor will switch off the output voltage and enter into a low power mode. When the input voltage rises again above the threshold, the supervisor will switch on the output voltage and return to its normal operating state. Based on the detection of the input voltage, the XC6123A345MR-G will also activate other protective measures, such as current limit, temperature protection and short circuit protection, in order to protect the system from potential damage. In addition, the XC6123A345MR-G is also equipped with a reset signal that can be used to help reset the system if it has entered an abnormal state. The reset signal can be triggered either manually or automatically depending on the particular application, and it is important to ensure that the supervisor operates in conjunction with the reset signal to ensure the most efficient and reliable operation.

Conclusion

The XC6123A345MR-G is a valuable asset for a variety of low voltage system applications. With its wide range of features and functions, it ensures the efficient and reliable operation of the system even under low voltage and high temperature conditions. The integrated protection functions further protect the system from potential damage caused by overvoltage, undervoltage, current overload and overtemperature conditions. In summary, XC6123A345MR-G can be an important part of any low voltage system application.
