BQ25703A Description
The bq25703A is a synchronous NVDC battery buckboost charge controller, offering low ponent 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 pletely discharged or removed.
