BQ27520YZFR-G2 is a member of Texas Instruments’ BQseries products and is a fully integrated gas gauge IC for monitoring and controlling a rechargeable Li-ion battery pack. It is an advanced battery monitoring IC that enables accurate tracking of vital parameters such as voltage, current, SoC, SoH, capacity, and temperature.

Application Fields

BQ27520YZFR-G2 has many applications in battery management. It can be used for machines, instruments and devices that require precise battery management to manage a full charging and discharging cycle, as well as to monitor the health of the battery at all times. Besides, it can also be used in industrial and automotive applications, such as medical instruments, smart meters, monitoring systems, etc.

Working Principle

BQ27520YZFR-G2 works with the help of an embedded power management unit (PMU), which continuously monitors, monitors, and regulates battery charge and discharge cycles and states. The PMU accurately detects the cell voltage, as well as the current and temperature information, which is then used to infer battery charge and discharge levels. This information is used to determine the SoC, SoH, capacity, and temperature of the battery. The chip also has an “End-of-Charge” and “End-of-Discharge” detection feature, which are used to ensure that the battery stays in a healthy, safe operating mode for the longest time possible.

At the same time, BQ27520YZFR-G2 has a large onboard RAM, which can store important data related to the battery’s health. This data includes information such as the Charge/Discharge cycles, State of Charge (SoC), State of Health (SoH), and the capacity of the battery. The chip also has two I2C/SMBus communication lanes, and features built-in Watchdog and Sleep Mode power-saving functions. This chip has a wide operating temperature range, and can operate from -20°C to +85°C. Overall, the BQ27520YZFR-G2 provides an all-in-one solution for battery management ICs.
