PMIC - Supervisors are electronic components used to ensure proper power delivery and prevention of power related errors. The XC6123D749ER-G is one of the many components that fit into this category of electronics. This guide provides an overview of the XC6123D749ER-G and explains its application field and working principle.

Application Field

The XC6123D749ER-G is a supervisor specialized in power systems. As a supervisor, it works to ensure proper power delivery between components. It prevents power related errors and malfunctions, such as those caused by power surges or voltage spikes, thus ensuring system stability and reliability. The XC6123D749ER-G features an onboard voltage regulator and an auto-reset feature that can be configured to different thresholds.

The XC6123D749ER-G is primarily used in high-end embedded systems, such as those in industrial or automotive applications. Its low power consumption and on-chip LDO make it suitable for low-power systems, such as those using tiny processors. In addition, its wide operating range and hot-swap/reset capability make it well-suited for processor-controlled systems.

Working Principle

The XC6123D749ER-G monitors the voltage of an onboard system and then, depending on the programmable threshold, either perform a reset if a malfunction occurs or adjust the onboard voltage regulator. This feature allows the device to be programmed to reset itself or to adjust the voltage of the system.

Once the device has been programmed with the threshold, it will continuously monitor the voltage state of the onboard system. Should the voltage exceed or fall below the programmed threshold, the XC6123D749ER-G will automatically reset or adjust the onboard voltage regulator. This ensures that the system remains stable and free from power related errors.

The XC6123D749ER-G is equipped with an auto-reset feature that can be configured to different thresholds. This allows the device to be programmed to reset the system or adjust the voltage regulator at different voltage states. Additionally, the device has an adjustable input voltage threshold that can be programmed to detect different voltages.

The XC6123D749ER-G can also support two types of reset: active-high and active-low reset. These two reset types activate different sets of pins on the device. The active-high reset is used when the system is experiencing a fault and requires reset, while the active-low reset is used when the system is functioning properly and doesn\'t require reset.

Lastly, because the XC6123D749ER-G features an integrated voltage regulator, it helps reduce power losses and avoid power disturbances in the system. This helps ensure proper power delivery and system stability.

Conclusion

The XC6123D749ER-G is a PMIC - Supervisors designed for high-end embedded systems. It monitors the voltage of an onboard system and can be programmed to either reset itself or adjust the voltage regulator. It also features an auto-reset feature, an adjustable input voltage threshold, and an integrated voltage regulator. This makes it suitable for embedded systems that require stable and reliable power delivery.
