BQ24298RTWR Description

Short technical summary and product information.

The BQ24298RTWR from Texas Instruments is a highly integrated single-cell USB charger IC designed for Li-Ion/Li-Polymer batteries. It supports a charge current of up to 3A and operates with an input voltage range of 3.9V to 6.2V, with an absolute maximum rating of 15V.

 

This device utilizes an I2C interface for control and features Narrow VDC (NVDC) Power Path Management, enabling instant system power-on even with no battery or a deeply discharged battery. It offers precise regulation with ±0.5% charge voltage accuracy and ±7% charge current accuracy. The charger includes comprehensive fault protection, including over current, over temperature, and over voltage protection.

 

The BQ24298RTWR is housed in a 24-WQFN (4x4 mm) package and is designed for surface mounting. It operates within a temperature range of -40°C to 85°C. Key features include thermistor monitoring for battery temperature, IC thermal regulation, and input current limiting that supports USB 2.0 and USB 3.0 standards.

 

Additional functionalities include USB OTG (On-The-Go) support with adjustable output voltage and fast startup, as well as a 1.5-MHz switching frequency for a low-profile design. The device is suitable for applications requiring efficient and reliable battery charging solutions.
