BQ24072RGTT

Battery Chargers Overview

The BQ24072RGTT is a single-cell lithium-ion battery charger and power-path management IC from Texas Instruments. It operates within an input voltage range of 4.3 V to 6.4 V, supporting a maximum output current of 1.5 A. The device regulates the charging voltage to 4.2 V for standard Li-ion cells. It utilizes a 16-pin VQFN package with dimensions of 3.15 mm x 3.15 mm. The component functions across a temperature range of -40°C to +85°C.

Battery Chargers Feature Summary

• Integrates power-path management to prioritize system load over battery charging when input current is limited.
• Includes automatic recharge functionality that resumes charging when battery voltage drops below the threshold.
• Features thermal regulation to reduce charge current based on die temperature to prevent overheating.

Battery Chargers Applications

• Portable consumer electronics requiring USB-compatible charging
• Single-cell lithium-ion battery powered devices
• Power management systems in compact handheld equipment

Battery Chargers Procurement Notes

Verify the specific suffix RGTT against the manufacturer datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with RoHS directives if required by the target market. Confirm that the supplier provides traceability documentation for original Texas Instruments components to avoid counterfeit risks.

Battery Chargers Selection Notes

Select this component for applications requiring integrated power-path management to maintain system operation during high-load conditions. It is suitable for designs where input current limiting is necessary to comply with USB host specifications. Consider the small VQFN footprint for space-constrained PCB layouts.

Battery Chargers Part Context

This part belongs to the bqTINY III family of battery chargers. It is designed as a cost-effective solution for single-cell applications. The device combines linear charging technology with power-path control in a minimal footprint, targeting portable devices that require efficient power management from standard USB sources.

Battery Chargers Replacement Considerations

Check for BQ24072TRGTR or BQ24072RGTR as potential package variations within the same functional family. Verify pinout compatibility before substituting with other models in the BQ2407x series.
