The bq24726 is a high-efficiency, synchronous battery charger, offering low component count for space-constraint, mulTI-chemistry battery charging applicaTIons.
The bq24726 uTIlize charge pump to drive n-channel RBFET to improve system efficiency.
SMBus controlled input current, charge current, and charge voltage DACs allow for high regulaTIon accuracies that can be programmed by the system power management micro-controller.
The bq24726 uses internal input current register or external ILIM pin to throttle down PWM modulation to reduce the charge current.
The bq24726 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.
