The LTC6804HG-2#PBF is a battery management integrated circuit (IC) designed for use in high power applications. It belongs to a product class called PMIC – Battery Management, which is designed to manage the current, temperature, and other aspects of battery operations in order to optimize battery performance and extend its lifespan.

The LTC6804HG-2#PBF integrates 14 pairs of N-channel MOSFETs and two analog-to-digital converters into a programmable current and voltage monitor that measures, controls, and balances up to eight Li-Ion and LiPo cells. It is designed to provide a precision voltage, current, and temperature reference for each of the 8 channels, enabling it to be used in a variety of applications. In addition, it includes an adjustable current limit, cell protection under/over voltage lockout, and overtemperature/overcurrent protection for each of the channels.

The LTC6804HG-2#PBF supports a wide range of battery management applications, including those that require very high current and/or a wide operating temperature range. It is commonly used in electric and hybrid electric vehicles, consumer electronics, and medical devices, as well as any other application where battery management is critical. It is designed to allow engineers to implement a design that meets the specific requirements of their application and maximize system lifetimes and performance.

The LTC6804HG-2#PBF’s working principle is based on the concept of cell balancing. The integrated analog-to-digital converters (ADCs) measure the voltage of each cell, allowing it to detect imbalances in the battery’s charge and discharge rates. This allows the IC to identify possible issues with the battery, such as overcharging and overdischarging, and take corrective action to prevent more serious damage. In addition, it can be used to evenly disperse power distribution from one cell to another, ensuring a uniform charge/discharge rate across all cells, as well as provide advanced monitoring and protection for each cell.

In addition to cell balancing, the LTC6804HG-2#PBF also includes a range of additional features, such as overvoltage, undervoltage, overcurrent, and overtemperature protection. These safety features ensure that the connected cells and systems remain safe from damage due to extreme circumstances. For instance, the overvoltage protection ensures that a cell’s charge is kept within a safe range, while the overcurrent protection limits the amount of current that can flow through a channel to prevent damage.

Overall, the LTC6804HG-2#PBF is a powerful battery management IC designed to meet the needs of applications that require precise battery management and long-term reliability. Its integrated MOSFETS, ADCs, and safety features enable it to be used in a wide range of applications, while its precision voltage and current control features allow engineers to maximize system performance and battery life.
