BQ24073RGTR

Battery Chargers Overview

The BQ24073RGTR is a USB-friendly Li-Ion battery charger and power-path management IC from Texas Instruments. It supports a maximum charge current of 1.5A with an output voltage of 4.2V. The device operates within an input supply voltage range of 4.35V to 6.4V. It features programmable charge current and timer functions, along with fault protection including over-temperature, over-voltage, reverse current, and short-circuit safeguards. The component is housed in a 16-VQFN (3x3 mm) package with exposed pad for surface-mount installation.

Battery Chargers Feature Summary

• Integrates linear charging and system power path management for portable applications
• Complies with USB-IF surge current specifications through precise input current limiting
• Includes input dynamic power management to prevent errors from misconfigured USB power sources
• Provides comprehensive fault protection against thermal, electrical, and short-circuit conditions

Battery Chargers Applications

• Portable devices requiring space-constrained battery charging solutions
• USB-powered consumer electronics
• Single-cell lithium-ion battery systems
• Applications utilizing non-regulated AC adapters or USB ports

Battery Chargers Procurement Notes

Verify the specific suffix 'RGTR' corresponds to the tape-and-reel packaging configuration. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure ESD handling protocols are followed due to the moisture sensitivity level and small form factor. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Battery Chargers Selection Notes

Select this component when designing for single-cell Li-Ion batteries requiring up to 1.5A charging current. It is suitable for systems powered by standard USB interfaces or unregulated adapters within the 4.35V to 6.4V input range. Consider the 16-VQFN package size for PCB area constraints. Evaluate the need for programmable current settings and integrated power path management for system efficiency.

Battery Chargers Part Context

This part belongs to the BQ2407x family of Li-Ion battery chargers from Texas Instruments. The family includes variants like BQ24072, BQ24076, and BQ24079, which share similar functionalities but differ in input voltage ranges, charge currents, and package options. The BQ24073 specifically targets USB-friendly applications with a 1.5A capability.

Battery Chargers Replacement Considerations

Compatible substitutes within the same family include BQ24072RGTR and BQ24076RGTR. Verify that the alternative part's input voltage range and charge current specifications match the design requirements. Check for pin-to-pin compatibility if replacing on an existing PCB layout.
