The BQ24740RHDR from Texas Instruments is a high-efficiency, synchronous battery charger IC. It is designed for multi-chemistry battery charging applications, supporting two, three, or four series Li+ cells with charge currents up to 10A. The device features high-accuracy voltage and current regulation, with ±0.5% charge voltage accuracy and ±3% charge current accuracy.
This charger IC operates within a 5-24V AC/DC adapter input range and includes features like input overvoltage protection (OVP) and dynamic power management (DPM). It offers analog inputs for ratiometric programming of charge current and voltage, which can be controlled via resistors or a DAC/GPIO interface. The BQ24740RHDR is available in a compact 28-pin, 5x5mm VFQFN package, suitable for space-constrained designs.
Key applications include notebook computers, ultra-mobile computers, portable data-capture terminals, portable printers, and medical diagnostics equipment. The integrated compensation and soft-start features contribute to high regulation accuracies and a low component count.
