BQ24190RGER Description

Short technical summary and product information.

The Texas Instruments BQ24190RGER is a highly integrated single-cell USB/Adapter charger IC featuring I2C control. It is designed for Lithium Ion/Polymer batteries and supports a maximum charge current of 4.5A. The device operates with an input voltage ranging from 3.9V to 17V, with an absolute maximum rating of 22V.

 

Key features include a switch-mode buck control topology, a 1.5MHz switching frequency for a low-profile inductor, and high efficiency up to 92% charge efficiency at 2A and 90% at 4A. It also incorporates USB OTG functionality, providing 5V at 1.3A with 93% boost efficiency at 1A. The charger includes comprehensive fault protection such as over current, over temperature, and over voltage.

 

This IC is housed in a 24-VQFN (4x4) package and is suitable for surface mount applications. It offers precise regulation with ±0.5% charge voltage regulation and ±7% charge current regulation accuracy over a wide temperature range of -40°C to 85°C.
