Power Management Integrated Circuits (PMICs) are one of the most important components in modern electronics designs. They enable the efficient and reliable control of power and enable products to function reliably in the presence of changing temperatures, current, and voltage. PMICs are widely used in a range of applications from medical equipment to industrial automation. PMICs are divided into two main categories: Battery Management and Power Management.The Battery Management category is used to manage different types of batteries, including Lithium-Ion, Nickel-Metal Hydride, Nickel-Cadmium, and Lead-Acid. Battery Management PMICs have become popular in applications where size, weight and current capability are important constraints. The most important features of Battery Management PMICs include battery monitoring and protection, voltage conversion, and charging control.BQ29311PW is a Battery Management PMIC from Texas Instruments. This PMIC offers 4 channels of voltage monitoring, 4 channels of over-temperature protection, two multiplexers for voltage and temperature conversion, and charge control functions.
