BQ24075TRGTT

Battery Chargers Overview

The BQ24075TRGTT is a 1.5A USB-friendly Li-Ion battery charger and power-path management IC manufactured by Texas Instruments. It operates within an input voltage range of 4.35V to 6.4V, with a maximum input voltage tolerance of 26V without damage. The device provides a regulated output voltage of 4.2V for single-cell lithium-ion batteries and supports a programmable charge current up to 1.5A. It utilizes a 16-pin HVQCCN package (LCC16,.12SQ,20) with dimensions of 3mm x 3mm. The component functions across a temperature range of -40°C to +85°C and includes features such as a detection threshold voltage of 0.08V.

Battery Chargers Feature Summary

• Integrates power-path management to prioritize system load while charging the battery from USB or external adapters.
• Supports dynamic input current limiting to comply with USB host port specifications without requiring external components.
• Includes programmable pre-charge and termination timers for customizable charging profiles.

Battery Chargers Applications

• Portable consumer electronics powered by single-cell lithium-ion batteries
• USB-powered devices requiring integrated battery charging and system power distribution
• Mobile communication devices and handheld instruments

Battery Chargers Procurement Notes

Verify the specific suffix 'RGTT' corresponds to the tape-and-reel packaging format required for your assembly line. Confirm that the 16-VQFN footprint matches your PCB layout guidelines. Ensure compliance with RoHS directives and check the moisture sensitivity level (MSL 2) handling requirements during storage and soldering processes.

Battery Chargers Selection Notes

Select this component when designing systems that require a compact solution for single-cell Li-Ion charging directly from USB sources. It is suitable for applications needing integrated power-path management to maintain system operation during charging. Consider thermal performance constraints due to the small QFN package size when determining heat dissipation strategies.

Battery Chargers Part Context

This part belongs to the BQ2407x family of battery chargers from Texas Instruments, which includes variants like BQ24072, BQ24073, and BQ24079. These devices share similar core functionalities but may differ in specific electrical parameters or feature sets. The BQ24075 specifically targets standard 4.2V Li-Ion cells with a 1.5A charge capability.

Battery Chargers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative models such as BQ24079 or BQ24073 only if their datasheets explicitly state pin-to-pin compatibility and identical electrical characteristics for your specific application requirements.
