The BQ24745RHDRG4 is a high-efficiency, synchronous battery charger IC manufactured by Texas Instruments. Designed for space-constrained applications, it offers a low component count and supports multi-chemistry battery charging, including Li+, NiCd, NiMH, and Lead Acid. This device features a 24V AC/DC adapter operating range and can charge batteries with up to 19.2V.
Key electrical specifications include a charge current of 8.064A and a high operating frequency of 300kHz, contributing to over 95% efficiency. It supports 2 to 4 Li-Ion cells and provides high-accuracy voltage and current regulation. The charger integrates an input-current comparator and uses SMBus for programming input-current, charge-current, and charge-voltage DACs, allowing for precise control by a system microcontroller.
The BQ24745RHDRG4 is housed in a 28-pin VFQFN exposed pad package measuring 5x5 mm, suitable for surface mounting. It operates within a junction temperature range of -40°C to 125°C. The device includes fault protection for overvoltage conditions and features simplified SMBus control with status and monitoring outputs.
