TI BQ25890RTWR

锂离子/聚合物5A-40°C ~ 85°C（TA）

Overview

The bq25890, bq25892 are highly-integrated5-A switch-mode battery charge management and system power path management device for single cellLi-Ion and Li-polymer battery. The devices support high input voltage fast charging. The lowimpedance power path optimizes switch-mode operation efficiency, reduces battery charging time andextends battery life during discharging phase.

The device family is available in 24-pin, 4 x 4 mm2 x 0.75 mmthin WQFN package.
