BQ24192IRGER Description

Short technical summary and product information.

The BQ24192IRGER from Texas Instruments is a highly integrated, I2C-controlled, 1-cell buck battery charger designed for Lithium-Ion/Polymer batteries. It supports a charge current of up to 4.5A and features Narrow Voltage Direct Current (NVDC) Power Path management, enabling instant-on operation even with no battery or a deeply discharged battery.

 

This charger IC operates within an input voltage range of 3.9V to 17V, with an absolute maximum rating of 22V. It offers precise battery charge voltage regulation between 3.5V and 4.4V. Key electrical features include a typical charge efficiency of 92% at 2A and 93% boost efficiency at 1A. The device communicates via an I2C interface and includes comprehensive fault protection against over current, over temperature, and over voltage conditions.

 

Packaged in a 24-VQFN (4x4mm) with an exposed pad, the BQ24192IRGER is designed for surface mounting. Its operating temperature range is -40°C to 85°C. The charger incorporates features like battery temperature monitoring, input current limit (IINDPM), and USB OTG support, making it suitable for various portable power management applications.
