BQ24735RGRT Description

Short technical summary and product information.

The BQ24735RGRT from Texas Instruments is a high-efficiency, synchronous battery charger IC designed for 1-4 cell Li+ battery applications. It supports Intel CPU Turbo Boost mode by allowing the adapter and battery to provide power to the system simultaneously.

 

This device features an SMBus host-controlled NMOS-NMOS synchronous buck converter with programmable switching frequencies. Key electrical specifications include a maximum operating voltage of 24V, a battery pack voltage up to 16.8V, and charge voltage accuracy of ±0.5%. It also offers ±3% accuracy for charge current and input current.

 

Enhanced safety features include overcurrent, overvoltage, and short-circuit protection. The charger operates within a temperature range of -40°C to 85°C and is available in a 20-VQFN (3.5x3.5) surface-mount package.

 

Additional features include programmable input current, charge voltage, and charge current limits, as well as programmable adapter detection and indicator. The device also includes integrated loop compensation and soft start for smooth operation.
