♠ BQ25611D I2C Controlled 1-Cell 3.0-A Buck Battery Charger with USB Detection and 1.2-A Boost Operation
The BQ25611D is a highly integrated 3-A switchmode battery charge management and system power path management device for single cell Li-Ion and Lipolymer batteries. The solution is highly integrated with input reverse-blocking FET (RBFET, Q1), highside switching FET (HSFET, Q2), low-side switching FET (LSFET, Q3), and battery FET (BATFET, Q4) between system and battery. The low impedance power path optimizes switch-mode operation efficiency, reduces battery charging time and extends battery run time during discharging phase.
The BQ25611D is a highly integrated 3-A switchmode battery charge management and system Power Path management device for Li-ion and Li-polymer batteries. It features fast charging with high input voltage support for a wide range of applications including smart phones and tablets . Its low impedance power path optimizes switch-mode operation efficiency, reduces battery charging time, and extends battery run time during discharging phase.
