BQ2054SNTR Description

Short technical summary and product information.

The BQ2054SNTR from Texas Instruments is a specialized IC designed for the efficient and safe charging of Lithium Ion battery packs. It employs a flexible pulse-width modulation regulator to precisely control voltage and current during the charging process, ensuring optimal battery health.

 

The charging cycle includes a constant current phase, replenishing up to 70% of the battery's capacity, followed by a voltage-regulated phase to bring the battery to full charge. Termination of the charge cycle is managed by a user-selectable minimum current limit, with a safety backup for maximum charge time. The IC continuously monitors battery temperature and voltage, inhibiting charging if these parameters fall outside configured limits. It also provides low-current conditioning for batteries with voltages below a set threshold.

 

Designed for high efficiency, the switch-mode operation minimizes power dissipation. The BQ2054SNTR features direct LED control outputs to indicate charge status and fault conditions, aiding in accurate determination of the battery and charge system status. It is housed in a 16-SOIC package suitable for surface mounting.

 

Key features include voltage-regulated current-limited charging, selectable minimum current termination, and safety backup termination on maximum time. The device is qualified by temperature and voltage limits, and its charging process is optimized for Lithium Ion chemistry.
