XC6124C533MR-G

The XC6124C533MR-G is a low power Supervisior IC, manufactured by Toshiba. This chip was designed to provide basic over-voltage protection, under-voltage protection, and reset circuits for digital circuits in automotive, industrial and home applications. It provides a robust solution for ensuring that systems are always in a safe working state and mitigating damage during unexpected power anomalies.

Features

The XC6124C533MR-G incorporates several key features to make it ideal for protection, including a low operating current of 0.013μA, high input accuracy of ±0.8%, power source indicator, and under voltage lockout. Its operating voltage range of 2.5V to 5.5V also makes it an excellent choice for battery powered applications. It also provides a low voltage reset output and an open drain reset output for driving an external device such as an FET.

Application Field

The XC6124C533MR-G is widely used in automotive, industrial, and home applications. It is employed as an over-voltage and under-voltage protection in circuit boards, used to ensure that the system is always in a safe working state. It is also used in battery powered devices, where it is used to provide protection against low battery levels and power disruptions. Finally, it can be used in embedded systems to monitor the status of the system and ensure that key parameters are not exceeded.

Working Principle

The XC6124C533MR-G works by monitoring the supply voltage of an electronic system. Whenever the input voltage drops below the preset minimum threshold, the IC triggers an output event, providing a reset signal to an external device in order to reset the system. Alternatively, an output event can also be triggered when the supply voltage exceeds the set maximum threshold. This prevents the system from entering into an unstable state during over-voltage events. Additionally, the under voltage lockout (UVLO) feature prevents the chip from functioning properly until the voltage is above the set UVLO threshold. This is extremely useful in situations where the input voltage could be too low to allow the IC to function.

Conclusion

The XC6124C533MR-G is an excellent choice for providing basic over-voltage and under-voltage protection in automotive, industrial, and home applications. Its low operating current of 0.013μA and wide operating voltage range of 2.5V to 5.5V make it ideal for battery powered devices, while its UVLO feature ensures that the chip is protected from low voltage events. Furthermore, its reset outputs provide a robust solution for resetting systems during power anomalies, helping to mitigate risk and ensure reliable operation.
