Power - bq77910 Slide 15

In summary, the bq77910 is an integrated battery management solution for Li-ion based power tools, e-bikes, UPS systems, and other high-current applications. It provides all necessary battery pack protection functions as well as integrated cell balancing. And it operates as a stand-alone device without the need for an external microprocessor. The bq77910 was designed to meet the challenges of high-power applications. It is able to directly manage packs of up to ten cells in series, and has various safety and fault detection thresholds programmable in EEPROM that can be set up to work with any type of Lithium-ion battery. Because of the high currents and voltages, the device drives NMOS FET devices in the low side of the battery.
