PMIC - Battery Management: BQ7692003PWR

BQ7692003PWR is a rechargeable battery management integrated circuit (IC). It is a design with an integrated two-stage buck charger circuit that includes battery voltage monitoring and cell balancing. This integrated circuit is widely used in space-constrained battery-powered applications such as phones, portable medical devices and even some aircraft applications.The primary goal of this BQ7692003PWR application is to maintain the charge of the rechargeable batteries. It utilizes a two-stage buck charger circuit that is designed to maintain and optimize the voltage levels of the battery for it to charge more effectively and for a longer duration. This IC also features a built-in battery voltage monitoring as well as cell balancing for multiple cell applications.

Working Principles

The BQ7692003PWR is made up of two primary parts; the buck switch and the battery voltage monitor. The buck converter or switch is an integrated circuit (IC) that helps in converting a voltage from one value to another. For example, the buck switch helps in converting voltage from theInput voltage to the desired output voltage. The battery voltage monitor on the other hand, helps in monitoring and maintaining the desired battery voltage levels. The battery voltage monitor consists of reverse current protection, a self-regulation loop and the battery cell balancing systems. The reverse current protection prevents current from flowing back into the battery if the load draws too much power from the battery. The self-regulation loop is the mechanism that ensures that the output voltage is constantly kept within its limits while the battery is beingcharged and also when it is discharged. Lastly, the cell balancing system helps in equalizing charge among the cells of the battery. This feature helps prevent the battery from over charging or undercharging any of its cells.

Benefits and Features

The biggest benefit of the BQ7692003PWR IC is its space-efficient design. The design is such that it enables the IC to be used in even the smallest and most tightly packed applications. This makes it the ideal choice for applications that require a battery to primarily power them. Other features of this IC include the built-in safety features such as thermal protection and reverse current protection, adjustable charge voltage and current as well as LED indicators for indicating the state of the battery.
