Power management system has become an imperative component in most modern electronic products. As the performance of electronics improves and the amount of energy needed rises, managing and optimizing the power usage in a device has become an increasingly important component. Taking into account of this need, TI has provided a series of PMIC modules called BQ78PL116RGZR. Here, we will talk about the application field of BQ78PL116RGZR and its working principle.

BQ78PL116RGZR is a single Cell Fuel Gauge and Protection Integrated Circuit specifically designed for Li-ion/Polymer battery applications, featuring a high level of accuracy, flexibility, and wide range of operating temperature. This module is one of the best solutions for effective and safe battery management in terms of both charging and discharging. Due to its high accuracy, this module can provide accurate and reliable status about remaining capacity in a single cell battery, by measuring the battery voltage, current, and temperature at up to 8 different spots. This module can also provide health status about the battery cell for safety and performance optimization. Now, let\'s take a look at its application field.

BQ78PL116RGZR is mainly used in batteries that require extensive protection, including applications such as smartphones, laptops, tablets, and other consumer products. Its wide operation temperature and high accuracy are especially useful for devices used in extreme climates or applications where rechargeable battery performance needs to be maintained. In addition, due to its integrated protection feature, it can protect single cells from overcharge, over/under-voltage, and over/under-temperature.

Let us now take a closer look at the working principle of BQ78PL116RGZR. This module uses coulomb counting algorithm to measure the state of charge (SOC) in the battery. It measures both the current and the voltage to calculate the SOC, and then stores the results into non-volatile memory. Thus, it can deliver reliable and accurate results without any extra components. In addition, it also has high accuracy against temperature fluctuations, which can minimize errors due to external temperature change. Furthermore, the integrated protection features and wide temperature operating range of BQ78PL116RGZR makes it an ideal choice for long-lasting battery management.

To sum up, BQ78PL116RGZR is a powerful and reliable battery management module specifically designed for Li-ion/Polymer battery. Its ability to measure SOC, voltage and current accurately, combined with its high accuracy against temperature fluctuations, wide range of operating temperature, and integrated protection features, makes it one of the best solutions for lasting and reliable battery management. Therefore, it is often used in applications such as smartphones, laptops, and tablets.
