Description
General part information
BQ25700A Series
The bq25700A is a synchronous NVDC battery buck-boost 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. When load power exceeds input source rating, the battery goes into supplement mode and prevents the system from crashing.
The bq25700A charges battery from a wide range of input sources including USB adapter, high voltage USB PD sources and traditional adapters.
