1 Introduction

The BQ25790 is an integrated switched-mode buck-boost battery charge management device in WCSP package, intended for 1- to 4-series cell Li-ion and Li-polymer batteries. The charger features a narrow VDC architecture (NVDC) which allows the system to be regulated to a minimum value even if the battery is completely discharged. Additionally, the BQ25790 supports input source detection through D+ and D- which is compatible with USB2.0, USB3.0 power delivery, non-standard adapters and many high voltage adapters. With dual input source selection, USB OTG support and an integrated 16-bit multi-channel analog-to-digital converter (ADC), the BQ25790 is a complete charging solution.
