Description

IC BATTERY CHARGER LI-ION 8A VQFN-20
The bq24707 and bq24707A devices are highefficiency, synchronous battery chargers, offering low component count for space-constrained, multichemistry 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 IC uses the internal input current register or external ILIM pin to throttle down PWM modulation to reduce the charge current. The IC provides an IFAULT output to alarm if any MOSFET fault or input over current occurs. This alarm output allows users to turn off input power selectors when the fault occurs. Meanwhile, an independent comparator with internal reference is available to monitor input current, output current, or output voltage. The IC charges one-, two-, three-, or four-series Li+ cells, and is available in a 20-pin, 3.5 × 3.5 mm QFN package.
