Working Principle

The XC6124C640ER-G is a one-channel, low-dropout integrated voltage regulator and supervisor. It is capable of providing both voltage regulation and overvoltage protection. The voltage regulator aspect of the IC allows it to provide a regulated output voltage that is subject to adjustment, as well as providing current limiting, thermal shutdown, and reverse voltage protection. The supervisor aspect of the IC is designed to monitor one or more input voltages for overvoltage conditions or other pre-defined conditions and provide the appropriate protection.

The XC6124C640ER-G has an adjustable reference voltage that can be configured to control the output voltage of the IC. The output voltage can be adjusted over a range of up to 2.5V with a resolution of 0.0024%. The reference voltage can also be combined with an external resistor divider to provide a more precise adjustment.

In addition, the supervisor aspect of the XC6124C640ER-G provides real-time input voltage monitoring and overvoltage protection. It can monitor up to four input voltages, with an absolute maximum rating of 25V. It also provides programmable undervoltage and overvoltage protection up to 12.5V and 25V, respectively, with a selectable delay time and interrupt capability. The IC also provides thermal protection and reverse polarity protection.

Finally, the XC6124C640ER-G has low power consumption and a very low quiescent current of only 16µA, making it well suited for battery-powered applications. The IC also has a wide operating temperature range from -40°C to +85°C, allowing it to be used in a variety of different environments.

Conclusion

The XC6124C640ER-G is an all-in-one PMIC, providing both voltage regulation and overvoltage protection in one package. It is versatile and can be used in a variety of applications and environments. It is low power and has a wide operating temperature range, making it well suited for battery-powered and industrial applications. The XC6124C640ER-G is an ideal solution for systems requiring power management and protection.
