The BQ24703RHDR from Texas Instruments is a highly integrated battery charge controller and system power selector designed for notebook and sub-notebook PC applications. This device is capable of managing multi-chemistry batteries, including Li-Ion and Li-Polymer, supporting 2, 3, or 4 series cells.
Key electrical specifications include a maximum charge current of 10A, an input voltage range from 7V to 28V (with an absolute maximum of 30V), and a battery charge voltage range of 8.4V to 16.8V. The charger utilizes a switch-mode buck control topology and features a 300kHz integrated PWM controller for high efficiency. It offers precise control with ±0.4% charge voltage accuracy and ±4% charge current accuracy. The control interface is standalone and RC-settable.
This IC operates within a temperature range of -40°C to 85°C. It is available in a 28-VQFN (5x5) package and a 28-VFQFN Exposed Pad package, both designed for surface mounting. The BQ24703RHDR includes features like Dynamic Power Management (DPM) to minimize battery charge time by maximizing available adapter power, depleted battery detection, and a low 20µA sleep mode current.
It is suitable for applications requiring robust battery management and charging control, ensuring efficient and safe operation for portable electronic devices.
