BQ25890RTWR Description

The BQ25890RTWR is a highly-integrated 5-A switch-mode battery charge management and system power path management device for single cell Li-Ion and Li-polymer batteries. The BQ25890RTWR supports high input voltage fast charging. The low impedance power path optimizes switch-mode operation efficiency, reduces battery charging time, and extends battery life during discharging phase.
