XC6123F731MR-G

Power management integrated circuits (PMICs) help streamline the power requirements of various applications and protect the device from an overload. Supervisors are an essential type of PMIC, providing a safety feature that supervises the applied voltage and deactivates it in case it starts to drop or rise outside the prescribed levels. The XC6123F731MR-G is a CMOS fixed-voltage supervisor IC specifically developed for use in mobile power supply equipment. Its compact design and integrated protection functions make it suitable for use in a wide range of electronic circuits.

Functional Features

The XC6123F731MR-G provides a regulated output voltage and helps protect against overvoltage and/or overcurrent conditions. It can provide outputs of 1.8V and 3.3V, with a threshold voltage of 0.160V. The IC also features high accuracy, allowing it to accurately maintain the output voltage even under low-supply conditions and with minimal power consumption. Additionally, the XC6123F731MR-G features a temperature-compensated delay time, which helps keep the output voltage constant despite levels of ambient temperature.

Application Field

The XC6123F731MR-G is designed to be used in mobile power supplies, protection ICs and LED controllers. Its ability to control the output voltage regardless of the ambient temperature makes it an ideal choice for applications that must operate in extreme temperatures. Additionally, its low power consumption makes it suitable for use in low-power devices like mobile phones, cameras and many other electronic gadgets.

Due to its small size, the XC6123F731MR-G is also well suited for use in space-constrained applications, such as nano-electronics, energy harvesting systems and portable medical devices. In addition, it is designed to meet the requirements of the Automotive Electronics Council’s AEC-Q100 Grade 1 standard, making it an excellent choice for automotive applications.

Working Principle

The XC6123F731MR-G supervisor is based on a CMOS architecture and regulates the output voltage by comparing it against a voltage threshold. This voltage threshold is determined by two adjustable resistors and an internal reference voltage. When the output voltage exceeds the threshold, the supervisor IC turns off the output and sends a warning signal. If the voltage continues to rise, the supervisor IC turns off the power supply and maintains the output off until the overload ceases. This helps protect the circuit components from damage due to overvoltage. Similarly, if the output voltage is too low, the supervisor IC also sends out a warning signal and turns off the power supply to protect the circuit.

Conclusion

The XC6123F731MR-G is a low-power CMOS fixed-voltage supervisor IC designed for mobile power supplies. It offers highly accurate control of the output voltage, even under low-supply conditions and extreme temperatures. Its integrated protection mechanisms and AEC-Q100 Grade 1 certification make it an excellent choice for automotive applications as well as low-power devices, nano-electronics and energy harvesting systems. In addition, its small size and low power consumption make it well suited for use in space-constrained applications.
