Texas Instruments bq2477x SMBus NVDC Battery Charge Controllers are high-efficiency, synchronous, NVDC-1 battery charge controllers. Each offers low component count for space-constraint, multi-chemistry battery charging applications. The power path management allows the system to be regulated at battery voltage. It does not, however, 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.
