BQ24079TRGTT

Battery Chargers Overview

The BQ24079TRGTT is a standalone linear Li-ion battery charger manufactured by Texas Instruments. It operates within an input voltage range of 4.3 V to 6.4 V and delivers a maximum output current of 1.5 A. The device provides a fixed output voltage of 4.1 V, suitable for specific lithium-ion cell configurations. It features a low operating supply current of 1.5 mA and supports power dissipation up to 2.3 W. The component is housed in a VQFN-16 package designed for surface mount technology (SMD/SMT). It functions reliably across a temperature range from -40 °C to +85 °C.

Battery Chargers Feature Summary

• Integrates USB-friendly charge management with input dynamic power management to prevent damage from misconfigured USB power sources.
• Includes programmable input current limiting and startup sequencing to comply with USB-IF surge current specifications.

Battery Chargers Applications

• Portable consumer electronics requiring space-constrained charging solutions
• USB-powered devices needing compliant surge current handling
• Applications utilizing non-stabilized AC adapters or USB ports

Battery Chargers Procurement Notes

Verify the exact suffix against the manufacturer's official documentation to confirm pinout compatibility and thermal performance characteristics. Ensure that the selected variant matches the required output voltage specification of 4.1 V for the target battery chemistry. Confirm RoHS compliance status and moisture sensitivity level prior to assembly to maintain manufacturing integrity.

Battery Chargers Selection Notes

Select this component when a fixed 4.1 V output is required rather than the standard 4.2 V found in other family members like the BQ24075. Consider the VQFN-16 package size for PCB layout constraints. Evaluate the 1.5 A current limit against the battery capacity requirements. Verify that the input voltage range aligns with the available system power source capabilities.

Battery Chargers Part Context

This part belongs to the BQ2407xT series of Li-ion battery chargers from Texas Instruments. It shares architectural similarities with models such as the BQ24075 and BQ24076 but differs in its specific output voltage setting. The series is designed for portable applications, offering integrated system power path management and protection features within a compact footprint.

Battery Chargers Replacement Considerations

The BQ24075TRGTT serves as a direct functional substitute within the same package, though it outputs 4.2 V instead of 4.1 V. The BQ24076RGTR is another alternative in the series but also specifies a different output voltage. Cross-reference datasheets to ensure the voltage difference does not impact the specific battery cell being charged.
