- Autonomous cell balancing redistributes charge between cells to maximize pack capacity and extend overall battery cycle life
- Ultra-low quiescent power consumption minimizing self-discharge in protected battery packs during storage and standby
- Stackable architecture allowing daisy-chaining of multiple protection ICs for higher series cell count configurations
Applications
The PBQ7791500PWT is designed for portable power tools, e-bikes, and industrial battery packs using 3 to 5 series Li-ion cells where integrated cell balancing and protection reduce system complexity and BOM cost. It is used in energy storage modules, backup power supplies, and medical portable equipment requiring autonomous protection against overcharge, over-discharge, and overcurrent faults without requiring a host microcontroller. The stackable design also enables deployment in larger multi-cell battery systems such as light electric vehicles and industrial robotics platforms.
