XC6124C322ER-G Application Field and Working Principle

Introduction

The XC6124C322ER-G is a low-voltage power supply supervisor IC designed to monitor voltage levels of two system power supplies in devices such as DVD players and set-top boxes. As it is a "supervisor" IC, the XC6124C322ER-G shuts down voltages when the supply voltage is outside of the designated range. The XC6124C322ER-G is a member of the XC6124PMIC—Supervisor line of power management ICs developed by ROHM Semiconductor.

Application Field

The XC6124C322ER-G is a low-voltage power supply supervisor IC designed to monitor voltage levels of two system power supplies in devices such as DVD players and set-top boxes. It is designed to monitor and protect a system from voltage surges or drops, but since it does not directly control the voltage, it is not suitable for power supplies that require active regulation. As the device is targeted mainly at consumer electronics applications, it is designed to have very low power consumption and is capable of operating down to 2.5V. With its small package size, its flexibility makes it suitable for a wide range of compact applications.The XC6124C322ER-G also features several protective functions, including an “Under Voltage Lockout” (UVLO) function, in order to protect devices from abnormal power supply conditions. The UVLO function shuts down the device when the supply voltage falls below a preset level. The XC6124C322ER-G also includes a “Su-Lyze” function, which allows the user to select a range of input voltages and operating voltages depending on the application. The XC6124C322ER-G is suitable for a range of consumer electronic applications, including DVD players and set-top boxes, automotive applications, and more.

Working Principle

The XC6124C322ER-G is a low-voltage power supply supervisor IC designed to monitor voltage levels of two system power supplies in devices such as DVD players and set-top boxes. It is designed to monitor and protect a system from voltage surges or drops, but since it does not directly control the voltage, it is not suitable for power supplies that require active regulation. When the power supply reaches a certain voltage level, the XC6124C322ER-G begins to monitor the voltage levels of both the input and the output. It stores the voltage levels in its memory and compares them over time to detect any abnormalities. If the voltage difference falls outside of the range set by the user, the XC6124C322ER-G will generate a warning or shut down the power supply to protect the device. The XC6124C322ER-G also features several protective functions, including an “Under Voltage Lockout” (UVLO) function, in order to protect devices from abnormal power supply conditions. The UVLO function shuts down the device when the supply voltage falls below a preset level.

Conclusion

The XC6124C322ER-G is a low-voltage power supply supervisor IC designed to monitor voltage levels of two system power supplies in devices such as DVD players and set-top boxes. It is designed to monitor and protect a system from voltage surges or drops, but since it does not directly control the voltage, it is not suitable for power supplies that require active regulation. The XC6124C322ER-G is suited to a range of consumer electronic applications such as DVD players, set-top boxes, automotive applications and more. It also includes several protective functions including an “Under Voltage Lockout” (UVLO) capability to protect devices from abnormal power supply conditions. The XC6124C322ER-G is an efficient and reliable solution for low-voltage power supply monitoring in consumer electronics devices, and is designed to have very low power consumption and is capable of operating down to 2.5V. Its small package size and its flexibility makes it suitable for a wide range of compact applications.
