This device includes a stable power supply for a wide range of input/output voltages, and provides protection from overcurrent and overvoltage. It is available in both surface mount and through-hole designs, and is suitable for use in a variety of consumer electronics and industrial applications.

Application Field

XC6121E449ER-G can be used in a wide range of consumer electronics and industrial applications due to its flexibility in both surface mount and through-hole designs. It can be used for laptop battery charging, car audio systems, LED controllers, process control systems, security systems and other automation equipment, circuit protection, voltage monitoring, etc.

Working Principle

At the core of XC6121E449ER-G is its on-chip control module which consists of an on-board voltage detector and a voltage control logic. The voltage detector is able to constantly monitor the input/output voltages and sends the data to the voltage control logic which then regulates the output voltage. This module is capable of providing protection from over-voltage, over-current, and brownout. In addition to this, the device has an internal digital timer for detecting the input current over time. This timer measures the amount of time it takes for the input/output current to reach its maximum current level. This allows the device to automatically detect and reduce the input/output current to protect the device from short circuit or overload conditions.Moreover, XC6121E449ER-G internal control logic can be easily programmed by users to suit their requirements. The internal control logic can be programmed to suit the user’s desired current levels, set specific error thresholds, adjust the power supply frequency and activate different features as desired.

Conclusion

XC6121E449ER-G is a versatile Power Management IC (PMIC) that is suitable for a variety of consumer electronics and industrial applications. It provides protection from over-voltage, over-current, and brownout protection. It also has an internal digital timer for detecting the input/output current over time. Additionally, the internal control logic can be programmed to suit the user’s different requirements.
