The BQ24703PWR from Texas Instruments is a highly integrated battery charge controller and system power selector designed for notebook and sub-notebook PC applications. This IC supports multi-chemistry batteries, including Li-Ion and Li-Polymer, and can handle 2, 3, or 4 series cells.
Key electrical specifications include a maximum input voltage of 28V (absolute maximum 30V) and a maximum charge current of 10A. The device operates as a switch-mode buck converter with a charge voltage range of 8.4V to 16.8V. It features ±0.4% charge voltage accuracy and ±4% charge current accuracy, ensuring precise battery charging. The integrated 300kHz PWM controller contributes to high efficiency.
For power management, the BQ24703PWR utilizes Dynamic Power Management (DPM) to minimize battery charge time by maximizing the use of available wall-adapter power. It also includes features like depleted battery detection and indication, and a low 20µA sleep mode current for reduced battery drain.
The BQ24703PWR is available in a 24-TSSOP package, suitable for surface mounting. Its operating temperature range is -40°C to 125°C, making it suitable for various environmental conditions.
