3 Description
The bq25600 and bq25600D device are a highly-
integrated 3.0-A switch-mode battery charge
management and system power path management
device for single cell Li-Ion and Li-polymer battery.
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.
