Battery Chargers datasheet and documents for BQ24045DSQT

BQ24045DSQT

Battery Chargers Overview

The BQ24045DSQT is a single-cell lithium-ion and lithium-polymer linear charger integrated circuit manufactured by Texas Instruments. It operates within an input voltage range of 3.5 V to 28 V, supporting non-regulated adapters with input overvoltage protection. The device delivers a maximum output current of 1 A and provides a regulated output voltage of 4.35 V. It is housed in a 10-WSON (2x2 mm) surface-mount package designed for space-constrained portable applications.

Battery Chargers Feature Summary

Supports high-voltage chemical batteries with a 4.35 V output level
Integrates thermal regulation to manage junction temperature during charging
Features programmable pre-charge and termination current thresholds via external resistors
Includes comprehensive fault protection against overtemperature, overvoltage, and short circuits

Battery Chargers Applications

Smartphones and mobile communication devices
Personal Digital Assistants (PDAs)
MP3 players and audio devices
Low-power handheld electronic instruments

Battery Chargers Procurement Notes

Verify the specific suffix DSQT corresponds to the tape-and-reel packaging configuration required for your assembly line. Confirm that the 4.35 V output voltage aligns with your battery chemistry specifications, as this variant differs from standard 4.2 V models. Ensure compatibility with your system's input power source limits before finalizing procurement orders.

Battery Chargers Selection Notes

Select this component when designing for portable devices requiring support for high-voltage lithium chemistries up to 4.35 V. It is suitable for systems powered by USB ports or AC adapters where input voltages may exceed standard levels. Choose this part if your design requires programmable charge termination points and integration of thermal management within a compact 10-pin WSON footprint.

Battery Chargers Part Context

This device belongs to the bq2404x series of highly integrated linear chargers from Texas Instruments. The series targets space-limited portable applications, offering a complete solution for single-cell lithium-based batteries. The DSQT designation indicates the specific reel packaging format for automated manufacturing processes.
