BQ25970 - 8-A Switched Cap Fast Chargers

Datasheet Summary

Description

The BQ2597x is a 97% efficient, 8-A battery charging solution using a switched cap architecture.

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 across the cable.
  • Integrated programmable protection features for safe operation.
  • Input over-voltage protection (BUS_OVP).
  • Input over-current protection (BUS_OCP) with adjus.
