Texas Instruments BQ25708
The bq25708 is a synchronous NVDC battery buckboost charge controller, offering low component count, high efficiency solution for space-constraint, multi-chemistry battery charging applications. The NVDC-1 configuration allows the system to be regulated at battery voltage, but not drop below system minimum voltage. The system keeps operating even when the battery is completely discharged or removed.| Part No. | BQ25708 |
