SKY77910-11 Fully Integrated Battery Protection and Cell Balancing Solution
SKY77910-11
Texas Instruments (TI) today announced the industry's first fully integrated battery protection and cell balancing solution for Li-Ion and LiFePO4 battery packs. The bq77910 battery management and protection device can manage 4- to 10-cell battery packs and can stack 2 devices to protect 11- to 20-cell battery packs. The device not only simplifies battery pack design for e-bikes, e-scooters, portable garden tools, power tools, and uninterruptible power supplies (UPS), but can also be used to replace lead-acid batteries.
The bq77910 not only protects the battery pack by monitoring individual cell voltages, but also drives 2 N-channel power MOSFETs to interrupt current flow in the event of a fault. The product's fault detection and recovery criteria are fully programmable in non-volatile memory, making it applicable to all types of Li-Ion battery systems.
