It offers a variety of features, such as system voltage monitoring, voltage tracking, and over-voltage protection, as well as fault-tolerant architecture for reliable operation. This PMIC is designed to supply, monitor, and control power to a wide range of applications, from consumer electronics to industrial and automotive applications, in a variety of ways.The ACT8847QM211-T PMIC provides comprehensive, integrated power management and control, including system voltage monitoring, voltage tracking, and over-voltage protection. It also includes voltage tracking and output voltage monitoring, as well as advanced fault-tolerant architecture and protection features. In addition, the PMIC includes a 4-phase PMOS-based buck converter for scaling the output voltage. The ACT8847QM211-T also provides comprehensive monitoring, including system temperature and voltage levels, which allow for optimal operation.The working principle of the ACT8847QM211-T is straightforward. Its two primary components are a 4-phase PMOS-based buck converter, and a 16-bit high performance digital logic block. The buck converter, powered by an external PWM signal, is responsible for scaling the output voltage to the required level, while the digital logic block provides the voltage tracking, system voltage monitoring, and fault-tolerance.The power stage of the buck converter is able to output up to 2A of current, making it suitable for a variety of applications. The buck converter also contains an integrated 4-phase charge pump, allowing it to operate efficiently at low switch frequency. Additionally, the PMIC includes an integrated level shifter, allowing it to output higher voltages at a lower voltage supply.In addition to the voltage and current regulation capabilities, the ACT8847QM211-T also features a voltage tracking module for dynamic voltage scaling, as well as over-voltage protection and fault-tolerance features. The voltage tracking module is used to track the output voltage of the buck converter in order to ensure reliable system performance and power supply. The over-voltage protection feature prevents over-voltage damage due to an abnormal external load, while the fault-tolerance feature prevents permanent damage to the PMIC and load due to an incorrect external voltage.The ACT8847QM211-T PMIC is ideal for a wide range of applications, from consumer electronics to industrial and automotive applications. It is suitable for use in a variety of devices, such as digital cameras, scanners, digital video recorders, routers, cellular base stations, remote controls, as well as HVAC, automotive, and industrial control systems. Its combination of efficient power management and comprehensive monitoring capabilities make it an ideal choice for applications requiring reliable, high-performance power management.
