BQ27520YZFT-G3 is a type of battery management integrated circuit, or PMIC, capable of monitoring and managing a single cell, rechargeable lithium-ion battery. It integrates a fuel gauge, protection and balancing functions, and a charge controller in a 3mmx3mm, 24-pin package. Developed for a wide range of portable and wearable applications, such as fitness trackers, medical devices, and smart watches, this device offers improved performance, accuracy, reliability, and low quiescent current consumption as compared to competing solutions on the market.

The BQ27520YZFT-G3 integrates dedicated fuel gauge and protection function circuitry, and supports Analog, I2C, SMBus, and PMBus communication protocols. This device offers a combination of features and flexibility designed to meet the needs of the most demanding applications. It is capable of accurately measuring voltage, current, and temperature, and provides a host of safety protections, such as over discharge, overcharge, and over temperature.

The BQ27520YZFT-G3 also includes a battery balancing feature, allowing the device to control a low resistance switch between the negative and positive terminals of the battery to equalize their voltages and maintain the optimal health of the battery over time. The integrated charge controller allows the system to charge the battery at a safe rate and maintain a safe and accurate voltage. All configuration and monitoring registers are accessible through the various communication protocols, allowing manufacturers to adjust the charge parameters in real-time to optimize battery health and longevity.

The BQ27520YZFT-G3 is designed to allow for simple integration into a host of smart, low-power products. The low quiescent current consumption of this device allows it to deliver long running times and maintain an alarm mode for low-power applications. With its low-power operation and robust feature set, this PMIC is an excellent solution for today’s portable and wearable devices.
