BQ24195RGET

Battery Chargers Overview

The BQ24195RGET is a single-cell Li-ion/Li-polymer battery charger from Texas Instruments, housed in a VQFN-24 package. It supports an input voltage range of 3.9 V to 17 V and delivers up to 4.5 A output current with adjustable output voltage. The device integrates I2C control for configuration and features a narrow VDC power path. It operates within a temperature range of -40°C to +85°C.

Battery Chargers Feature Summary

• Integrates an I2C-controlled charge management controller for system configuration.
• Supports both USB host and wall adapter power sources via a dual-input architecture.
• Features a narrow VDC power path to optimize system power distribution during charging.

Battery Chargers Applications

• Portable computing devices such as tablets and ultrabooks
• Smartphones and mobile communication handsets
• Medical equipment requiring single-cell lithium battery charging

Battery Chargers Procurement Notes

Verify the specific suffix 'RGET' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the VQFN-24 footprint matches the design layout. Ensure compatibility with the intended I2C bus voltage levels and check for any regional compliance certifications relevant to the deployment market.

Battery Chargers Selection Notes

Select this component when a compact solution for single-cell batteries is needed with high input voltage tolerance up to 17 V. It is suitable for designs requiring precise digital control via I2C rather than analog pin programming. Consider thermal performance requirements due to the small package size and potential high current loads.

Battery Chargers Part Context

This part belongs to the BQ2419x family of chargers designed for portable electronics. It shares the VQFN-24 form factor with other variants like the BQ24196 but differs in specific electrical characteristics and feature sets. The family targets applications needing efficient power path management and compact footprints.

Battery Chargers Replacement Considerations

The BQ24196RGET is a documented substitute within the same series. Verify functional equivalence regarding the narrow VDC power path and I2C register compatibility before substitution. Check if the alternative meets all thermal and current specifications for the specific application.
