BQ24725 SMBus Charge Controllers

Texas Instruments bq24725 SMBus charge controllers are high-efficiency, synchronous battery charger offering low component count for space-constrained, multi-chemistry battery charging applications. The TI bq24725 SMBus charger IC uses two charge pumps to separately drive n-channel MOSFETs (ACFET, RBFET, and BATFET) for automatic system power source selection. The bq24726 utilizes the charge pump to drive an n-channel RBFET to improve system efficiency. The TI bq24725 and bq24726 SMBus charge controllers use internal input current register or external ILIM pin to throttle down PWM modulation to reduce the charge current. The TI bq24725 and bq24726 SMBus controllers charge two, three, or four series Li+ cells.
