TI introduces industry's first single-chip battery management device for power tools and e-bike applications

Texas Instruments Incorporated (TI) (NYSE:TXN) today introduced the industry's first fully integrated battery protection and cell-balancing solution for Li-Ion and lithium iron phosphate battery packs. The bq77910 battery management and protection device can manage 4- to 10-cell battery packs, and two devices can be stacked to protect 11- to 20-cell packs. The device simplifies battery pack designs for e-bikes, e-scooters, portable gardening tools, power tools and uninterruptible power supplies (UPS) and can also be used when replacing lead acid batteries. For samples and evaluation modules, visit www.ti.com/bq77910-preu. The bq77910 protects the battery pack by monitoring individual cell voltages and drives two N-channel power MOSFETs to interrupt current flow during fault conditions. Fault detection and recovery criteria for the device are fully programmable in non-volatile memory to suit all types of lithium battery systems. Key features and benefits of the bq77910
