BQ24192RGET Description

Short technical summary and product information.

The BQ24192RGET from Texas Instruments is an advanced battery charger IC designed for 1-cell Li-Ion/Li-Polymer batteries. It features a maximum charge current of 4.5A and utilizes an I2C interface for control.

 

This charger supports a wide input voltage range from 3.9V to 17V, with an absolute maximum of 22V. The battery charge voltage can be set between 3.5V and 4.4V. Key features include BAT temperature monitoring, input current limit (IINDPM), input over-voltage protection (OVP), and integrated Power Path and USB OTG functionality.

 

The device operates as a switch-mode buck converter with a 1.5MHz switching frequency, contributing to high efficiency. It offers charge efficiencies of 92% at 2A and 90% at 4A. The NVDC power path management allows for instant-on operation even with no battery or a deeply discharged battery.

 

Packaged in a 24-VQFN (4x4 mm) with surface mount type, the BQ24192RGET operates within a temperature range of -40°C to 85°C. It includes fault protection for over current, over temperature, and over voltage conditions.
