BQ25971, 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
BQ25971 Features
* 1 97% Efficient power stage for 8-A fast charge
* Patent pending switched cap charger architecture optimized for 50% duty cycle
* Input voltage is 2x battery voltage (3.5 V to 4.65 V)
* Output current is 2x of input current (up to 4.5 A)
* Reduces power loss
