A Power Management Integrated Circuit (PMIC) is a specialized electronic component designed to manage power requirements in various devices. It regulates voltage levels, controls power distribution, and optimizes battery usage, ensuring that electronic systems operate efficiently. PMICs are commonly found in smartphones, tablets, and laptops, where they help extend battery life and improve performance. These circuits can integrate multiple functions, such as voltage regulation, battery charging, and power sequencing, into a single chip. By consolidating these functions, PMICs reduce the size and complexity of electronic designs, making them essential for modern devices that require compact and efficient power solutions.
