bq25601 Description
The BQ25601 is a highly-integrated 3-A switch-mode battery charge management and system power path management device for single cell Li-ion and Lipolymer batteries. 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...
