BQ25970 8-A Switched Cap Fast Chargers

Description The BQ2597x is a 97% efficient, 8-A battery charging solution using a switched cap architecture. This architecture and the integrated FETs are optimized to enable a 50% duty cycle, allowing the cable current to be half the current delivered to the battery, reducing the losses over the charging cable...
Features
•1 97% Efficient power stage for 8-A fast charge
