BQ25970 Datasheet (Texas Instruments) - 8-A Switched Cap Fast Chargers

BQ25970, 8-A Switched Cap Fast Chargers

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
