BQ24770RUYR

具有系统功率监控器和处理器热指示器的 1 至 4 节 SMBus NVDC 电池充电控制器 28-WQFN -40 to 85

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.

The bq2477x monitors adapter current IADP, battery charge/discharge current IBAT and system power PMON. The flexibly programmed PROCHOT output goes directly to CPU for throttle back when needed.
