Introduction

The XC6124D319MR-G is a widely used Power Management and Integrated Circuit (PMIC) device specifically designed to protect circuits against over-current and over-voltage conditions. Supervisors are particularly important components in power systems since they are responsible for ensuring the reliability of powering and performing system reset functions when needed. The XC6124D319MR-G works as a supervisor, by monitoring the supply rails in order to protect circuits and prevent system failure. In this article, we take a closer look at the application field and working principle of the XC6124D319MR-G.

Application Field

The XC6124D319MR-G is designed to protect circuits from over-current and over-voltage conditions. This is mainly used in consumer electronics, such as laptops, smartphones and tablets, in order to protect the power system from any sudden current spikes or voltage drops. It is specially designed to allow for high-performance, low power consumption, low-cost and high-accuracy with regard to voltage and current measurements. As such, it is used by many electronic manufactures in their products, ensuring safe and reliable operation.

Working Principle

The XC6124D319MR-G uses a two-input comparator operating with inputs of H and L. H is connected to the monitored voltage or current value and L is the set voltage or current threshold. When the monitored value is equal to or higher than the set value, an output signal or a reset signal is generated. The XC6124D319MR-G also includes a reference voltage that sets the accepted range of input voltages and currents.The XC6124D319MR-G also features a boost circuit that allows the input voltage to be easily converted between 0.7V to 5.5V. This is particularly important for systems that require a wide range of input voltages, such as laptops and tablets. The XC6124D319MR-G also supports auto-reset and manual-reset modes and can be triggered by a voltage or a current source.

Conclusion

The XC6124D319MR-G is a widely used Power Management and Integrated Circuit (PMIC) device specifically designed to protect circuits from over-current and over-voltage conditions. Supervisors are particularly important components in power systems since they are responsible for ensuring the reliability of powering and performing system reset functions when needed. The XC6124D319MR-G is used in consumer electronics, such as laptops, smartphones and tablets, working on a two-input comparator with inputs of H and L. It also features a boost circuit, auto-reset and manual reset modes and can be triggered by a voltage or a current source. These features make the XC6124D319MR-G an ideal choice for any device which requires reliable protection from over-voltage and over-current conditions.
