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.
BQ25890RTWR Features
Input Current Optimizer (ICO) to Maximize Input Power without Overloading Adapters
Resistance Compensation (IRCOMP) from Charger Output to Cell Terminal
Highest Battery Discharge Efficiency with 11-mΩ Battery Discharge MOSFET up to 9 A
Integrated ADC for System Monitor(Voltage, Temperature, Charge Current)
BATFET Control to Support Ship Mode, Wake Up, and Full System Reset
