BQ24297RGER Description

Short technical summary and product information.

The Texas Instruments BQ24297RGER is a highly integrated, I2C controlled, single-cell battery charger IC designed for Li-Ion/Li-Polymer batteries. It delivers a maximum charge current of 3A and operates within an input voltage range of 3.9V to 6.2V, with an absolute maximum rating of 15V.

 

This charger features Narrow VDC (NVDC) power path management, allowing for instant system power-on even with a deeply discharged battery. It includes USB On-The-Go (OTG) functionality with adjustable output voltage and supports USB battery charger specifications like BC1.2 for D+/D- detection. The device offers high efficiency with its switch-mode buck topology and a 1.5-MHz switching frequency.

 

Key electrical specifications include a battery charge voltage range of 3.5V to 4.44V, with high accuracy charge voltage regulation of ±0.5%. It also provides ±7% charge current regulation and ±7.5% input current regulation. The operating temperature range is -40°C to 85°C.

 

The BQ24297RGER is supplied in a 24-VQFN (4x4mm) surface-mount package. It incorporates essential safety features such as battery temperature monitoring, IC thermal regulation, input overvoltage protection, and MOSFET over-current protection.
