Description

The bq24780S device is a high-efficiency, synchronous battery charger, offering low component count for space-constrained, multi-chemistry battery charging applications.

The bq24780S device supports hybrid power boost mode (previously called andquot;turbo boost modeandquot;). It allows battery discharge energy to system when system power demand is temporarily higher than adapter maximum power level. Therefore, adapter does not crash.

The bq24780S device uses two charge pumps to separately drive N-channel MOSFETs (ACFET, RBFET, and BATFET) for automatic system power source selection.

Through SMBus, system power management microcontroller programs input current, charge current, discharge current, and charge voltage DACs with high regulation accuracies.

The bq24780S device monitors adapter current (IADP), battery discharge current (IDCHG), and system power (PMON) for host to throttle back CPU speed or reduce system power when needed.

The bq24780S device charges 1-, 2-, 3-, or 4-series Li+ cells.
