PMIC, or Power Management Integrated Circuits (ICs), are specialized components within electronic systems that manage and regulate the power supply. Their main functions include ensuring that devices receive the correct amount of power at the right time and optimizing energy use to extend battery life. PMICs are critical for a broad range of electronic products, from smartphones and portable devices to larger home electronics and industrial machinery. They monitor and control various aspects like voltage levels, current flow, and power-down sequencing, thereby protecting devices from power-related issues and improving their performance and efficiency.
Within the realm of PMICs, Power Supply Controllers and Monitors stand as vital subcategories that specifically control the distribution and monitoring of power within electronic circuits. These components are designed to provide precise power regulation and real-time monitoring, ensuring stability and reliability of the power supply to the critical sections of electronic devices. Their primary characteristics include low power consumption, high accuracy, and advanced protection features against overvoltage, undervoltage, overheating, and short circuits. Key manufacturers of PMIC - Power Supply Controllers, Monitors include Texas Instruments, Analog Devices, Inc., ON Semiconductor, Infineon Technologies AG, and Maxim Integrated.
