BQ25896RTWT

TEXAS INSTRUMENTS  BQ25896RTWT  芯片, 电池充电器, 锂离子/聚合物, 0.25A, WQFN-24

The is a highly integrated 3A switch-mode Battery Charge Management and System Power Path Management Device for single cell Li-ion and Li-polymer battery. It 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. The I²C serial interface with charging and system settings makes the device a truly flexible solution. It features fast charging with high input voltage support for a wide range of smartphone, tablet and portable devices. Its low impedance power path optimizes switch-mode operation efficiency, reduces battery charging time and extends battery life during discharging phase. It also integrates Input Current Optimizer ICO and Resistance Compensation IRCOMP to deliver maximum charging power to battery.
