Power management integrated circuits (PMICs) are devices that play an important role in many devices, from smartphones and home appliances to electric vehicles and industrial automation solutions. PMICs help conserve energy, optimize battery life, and reduce system costs. They make it possible for people to use a range of connected equipment and make their lives more convenient and comfortable. One of the specialized types of PMICs are battery management ICs (BMSs), which are critical components for safely charging and monitoring the performance of batteries in the demanding environment of a wide variety of applications.

The Texas Instruments BQ27531YZFT-G1 is a single-cell lithium-ion or lithium-polymer battery Fuel Gauge standard-voltage product. It has an integrated step-based fuel gauge that can monitor the charge and discharge of the battery to calculate its capacity, current, and remaining life. The device operates with a minimum operating voltage of 2.7 V and a maximum operating voltage of 4.35 V. It can tie the fuel gauge to the linear system, enabling the reading of an approximation of the SoC, voltage and temperature of the battery in real time.

The BQ27531YZFT-G1 is designed to accurately track battery characteristics such as the chemistry, capacity, state-of-charge (SoC), and remaining usable capacity. The IC is capable of monitoring battery charge current as well as discharge current, and running integrated safety checks such as charging overvoltage and temperature protection.

This battery-status IC is suitable for use in a variety of applications such as smartphones, tablets, industrial controllers and medical devices, offering superior battery and charge-discharge management performance.
