PMIC, or Power Management IC, is an essential component on virtually any system platform. It provides the necessary voltage and current levels needed to bridge the gap between the processor, the operating system, the peripherals, and the interacting components with the system. The XC6124A343MR-G is an advanced, PMIC-integrated supervisor and power supply controller developed to ensure system-level robustness, as well as to protect other components from damage or malfunction due to power losses or shortages. This particular device provides a variety of features such as a five-channel voltage supervisor, over-temperature and over-voltage protection, a 16-channel pulse-width modulated (PWM) controller, a green-mode DC/DC converter, and a channel-selectable linear regulator.

Application Field

The XC6124A343MR-G is suitable for a wide range of applications, including embedded systems for industrial, automotive, aerospace, and telecommunication applications. This device can easily be integrated into various system-on-chip/multi-chip packages, providing a single-package solution. It is also suitable for other portable applications, such as tablets and smart phones, where power savings and fast response to temperature changes are essential. Furthermore, its small size (3.95 mm x 4.40 mm) allows it to be used in space-constrained applications without any difficulty.

Working Principle

The XC6124A343MR-G is an advanced power supply controller with an integrated five-channel voltage supervisor and a 16-channel PWM controller. It is capable of dynamically switching between a high-performance mode and a green-mode power-saving mode, depending on the detected load. This allows power consumption to be reduced when in idle or low duty-cycle states. The integrated over-voltage and over-temperature protection circuitry guarantees a stable system operation and protects the other components of the system from damage due to power losses or shortages. The XC6124 allows for dynamic voltage scaling (DVS) to be used, allowing the user to customize the power-up and power-down parameters according to their needs.

The XC6124A343MR-G also integrates a green-mode DC/DC converter and a channel-selectable linear regulator, allowing for a higher degree of flexibility compared to other PMICs. The DC/DC converter provides a regulated output voltage with minimum power consumption. The linear regulator, on the other hand, ensures linear regulation of the output voltage regardless of the load, allowing for easy implementation of various voltage levels without any compromise on efficiency. In addition, the circuit also supports a multi-channel mode that allows for different voltage levels to be applied to different channels within the same system.

The XC6124A343MR-G is also equipped with high-performance monitoring and diagnostic features. The Voltage Stuck-Action Monitoring (VCAMS) feature monitors the power-on and power-off operation of the voltage supervision circuit, detecting a stuck-on or stuck-off condition. The Device Statistics Monitoring (DSM) function provides detailed performance data, including the measured supply current, temperature, and the output voltage level.

In summary, the XC6124A343MR-G is an advanced, integrated PMIC that provides system-level robustness, improved power management efficiency, and flexibility compared to other available PMICs. Its integrated voltage supervisor, PWM controller, green-mode DC/DC converter, and linear regulator enable it to be easily integrated into any system platform, allowing for dynamic voltage scaling and improved performance.
