1 Introduction
The BQ25672 is an integrated switched-mode buck battery charge management device in QFN package. It
is intended to charge 1S to 4S cell Li-ion and Li-polymer batteries. The charger features a narrow voltage
DC architecture (NVDC) which allows the system to be regulated to a minimum value even if the battery is
completely discharged. With dual input source selection, OTG support, and an integrated 16-bit multi-channel
analog-to-digital converter (ADC), the BQ25672 is a complete charging solution.
