The Texas Instruments BQ25700 Series—including BQ25700, BQ25700A, BQ25700RSNR, BQ25703, BQ25708, BQ25710, and BQ25713—comprises advanced buck–boost battery charger controllers for 1–4 cell Li-Ion and Li-Polymer batteries. Designed for notebooks, ultrabooks, and embedded power systems, these ICs offer intelligent system power path management, high-efficiency switching, and programmable charging through I²C or SMBus communication.
The devices support a wide input voltage range (3.5 V – 26 V) and dynamically manage system power to maintain stable operation during adapter, USB, or battery transitions. Their integrated MOSFET drivers enable compact, efficient power design suitable for high-performance portable electronics.
