BQ24297RGET Description

Short technical summary and product information.

The BQ24297RGET from Texas Instruments is a highly integrated, I2C controlled battery charger IC. It is designed for single-cell Lithium Ion/Polymer battery applications, capable of delivering a maximum charge current of 3A.

 

This device operates with an input voltage range of 3.9V to 6.2V, with an absolute maximum input voltage of 15V. It features a switch-mode buck control topology and supports battery charge voltages between 3.5V and 4.44V. The charger includes advanced features such as input current limiting, input overvoltage protection, and thermal regulation. It also provides USB OTG (On-The-Go) functionality with an adjustable output voltage from 4.55V to 5.5V at up to 1.5A.

 

The BQ24297RGET offers high accuracy in its charge voltage (±0.5%), charge current (±7%), and input current (±7.5%) regulation. It operates at a switching frequency of 1.5MHz, enabling the use of low-profile inductors. The device is housed in a 24-VQFN (4x4) package and is designed for surface mount.

 

Key safety features include overcurrent protection via Hiccup Mode, over-temperature protection, and input/system overvoltage protection. The operating temperature range is from -40°C to 85°C.
