The BQ24735RGRR from Texas Instruments is an active mode battery charge controller IC. It is designed for 1 to 4 cell Li-Ion/Li-Polymer battery chemistries and supports SMBus control interface. This device features a switch-mode buck topology and is capable of supporting Intel CPU Turbo Boost Mode by allowing the adapter and battery to provide power to the system together.
Key electrical specifications include an input voltage range of 4.5V to 24V, with an absolute maximum rating of 30V. The maximum charge current is 8A, and the battery charge voltage can range from 1.024V to 19.2V. The device operates within a temperature range of -40°C to 85°C. It also offers features like programmable input current, charge voltage, and charge current limits, with high accuracy for these parameters.
Packaged in a 20-VQFN (3.5x3.5) format, the BQ24735RGRR is designed for surface mount applications. It includes enhanced safety features such as overvoltage protection, overcurrent protection, and short-circuit protection for the battery, inductor, and MOSFETs. The SMBus host-controlled synchronous buck converter operates at programmable switching frequencies of 615, 750, and 885 kHz.
