BQ24707 SMBus Charge Controller The Texas Instruments BQ24707 SMBus charge controller is a high-efficiency, synchronous battery charger, offering low component count for space-constrained, multi-chemistry battery charging applications. SMBus controlled input current, charge current, and charge voltage DACs allow for very high regulation accuracies that can be easily programmed by the system power management micro-controller. The TI 24707 SMBus charge controller uses the internal input current register or external ILIM pin to throttle down PWM modulation to reduce the charge current. The BQ24707 provides an IFAULT output to alarm if any MOSFET fault or input over current occurs. This TI device is ideal for portable notebook computers, PDAs, handheld terminals, and more.
