Working Principle
The BQ24166YFFT is a synchronous PWM buck converter, which allows it to accurately measure the battery\'s voltage and current. It then uses this information to intelligently adjust the output voltage and current, based on the proscribed rail voltage and limit of the device. The device also includes a linear charger, which is used to ensure that the battery is always charged to the appropriate level. The linear charger operates by keeping the voltage of the battery below the specified level, while also ensuring that the current is also kept to the appropriate level. To regulate temperature, the device includes a regulated temperature portfolio. This portfolio is used to monitor the temperature of the battery at all times and to keep it from getting too hot. Finally, an active-clamp flyback charger is included to ensure the proper flow of power when the device is in use for long periods of time. The active-clamp flyback charger actively limits the current based on the amount of charge in the battery.

Conclusion
The BQ24166YFFT is an ideal solution for applications that require a single charger and battery stack controller. It is a reliable and efficient device that has a high level of accuracy when measuring the voltage and current of the battery. In addition, it includes a linear charger, a regulated temperature portfolio, and an active-clamp flyback charger to ensure the battery is always charged to the appropriate level and that the temperature is kept to a safe level. Ultimately, the BQ24166YFFT is a versatile and reliable device that can be used in a variety of applications, ranging from automotive to medical. It is the perfect solution for applications where space and power efficiency are important features.
