The BQ24740 is a high-efficiency, synchronous battery charger from Texas Instruments, designed for multi-chemistry battery charging applications. It offers integrated compensation and a low component count, making it suitable for space-constrained designs.
This charger supports two, three, or four series Li+ cells, with a charge current capability of up to 10A. It operates within an AC/DC adapter input voltage range of 5V to 24V. Key electrical specifications include high accuracy for charge voltage (±0.5%), charge current (±3%), and adapter current (±3%). It also features a 300kHz switching frequency and a maximum effective duty cycle of 99.5%.
The BQ24740 is available in a compact 28-pin, 5x5mm thin QFN package, designed for surface mounting. Its operating temperature range is from 0°C to 85°C.
Features include Dynamic Power Management (DPM) with status indication, input overvoltage protection (OVP), and low input power detection. It supports analog inputs with ratiometric programming via resistors or DAC/GPIO, allowing for flexible host control of charge voltage and current.
