Add To BomBQ24735RGRR General Description
The bq24735 device is a high-efficiency, synchronous battery charger, offering low component count for space-constrained, multichemistry battery charging applications. The bq24735 device supports turbo boost by allowing battery discharge energy to the system when system power demand is temporarily higher than the adapter maximum power level so the adapter will not crash.
The bq24735 device uses two charge pumps to separately drive N-channel MOSFETs (ACFET, RBFET, and BATFET) for automatic system power source selection.
SMBus controlled input current, charge current, and charge voltage digital-to-analog converters (DACs) allow for very high-regulation accuracies that can be easily programmed by the system power management microcontroller.
The bq24735 device uses an internal input current register or an external ILIM pin to throttle down PWM modulation to reduce the charge current. The bq24735 device charges 1-, 2-, 3-, or 4-series Li+ cells.
