BQ24735 – BQ735

The BQ735 is a 1- to 4-cell Li+ battery SMBus charge controller from Texas Instruments. It is designed to support Intel® CPU Turbo Boost Mode and features a number of advanced features, including:

• Automatic N-Channel MOSFET selection of system power source from adapter or battery driven by I2C interface
• SMBus-controlled NMOS-NMOS synchronous buck converter with programmable 615-, 750-, and 885-kHz switching frequencies
• Power management features such as input current limiting, output voltage regulation, and thermal protection
• Battery safety features such as overcharge protection, overdischarge protection, and short-circuit protection

The BQ735 is a popular choice for battery charge controllers in laptops and other portable devices because of its high integration, advanced features, and small size.

Here are some of the benefits of using the BQ735:

• Improved system performance: The BQ735’s support for Intel® CPU Turbo Boost Mode allows laptops to deliver higher performance when needed.
• Increased power efficiency: The BQ735’s synchronous buck converter helps to improve power efficiency by reducing the power loss associated with switching external switches.
• Enhanced system reliability: The BQ735’s power management and battery safety features help to improve system reliability by protecting the laptop and its battery from damag
