BQ25971 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
