Description
General part information
BQ24770 Series
The bq2477x is high-efficiency, synchronous, NVDC-1 battery charge controllers, offering low component count for space-constraint, multi-chemistry battery charging applications.
The power path management allows the system to be regulated at battery voltage but does not drop below system minimum voltage (programmable). With this feature, the system keeps operating even when the battery is completely discharged or removed. The power path management allows the battery to provide supplement current to the system to keep the input supply from being overloaded.
The bq2477x provides drivers and power path management for N-channel ACFET and reverse blocking FET. The devices provides driver to control NVDC operation of external P-channel battery FET. It also drives high-side and low-side MOSFETs of the switching regulator.
