Power Management Integrated Circuits (PMIC) are a type of integrated circuit specifically designed to manage and control the power supply in electronic devices. Their main function is to ensure that various components in electronic devices can operate at the correct voltage and current levels, while improving energy efficiency, reducing power consumption, extending battery life, and providing power conversion and distribution in some cases.
The main functions of the power management chip include:
Voltage regulation: Convert the power supply voltage into different voltage levels required by electronic devices through DC-DC converters.
Current limitation: Limiting the current passing through a circuit to protect electronic components from overcurrent damage.
Power Conversion: Converting one form of power source (such as alternating current (AC)) to another form (such as direct current (DC)).
Power distribution: In complex electronic systems, power is distributed to different subsystems and components.
Battery management: Monitor and manage the charging and discharging process of batteries to extend their lifespan and ensure safety.
Power monitoring: Real time monitoring of power status, including voltage, current, and power, and providing protection in case of abnormal conditions.
Energy recovery: In certain applications, such as automotive electronics, power management chips can recover and reuse energy.
Thermal management: Monitor the temperature of electronic devices and take measures to prevent overheating, such as adjusting power supply or activating cooling systems.
Power management chips are widely used in various electronic devices, including smartphones, laptops, tablets, household appliances, industrial control systems, automotive electronics, medical equipment, etc. As electronic devices become increasingly complex, the role of power management chips is becoming more and more important.
