Battery Chargers datasheet and documents for BQ24155RGYR

BQ24155RGYR

Battery Chargers Overview

The BQ24155RGYR is a fully integrated switch-mode single-cell lithium-ion battery charger manufactured by Texas Instruments. It operates within an input voltage range of 4 V to 6 V and delivers a maximum output current of 1.2 A. The device supports regulated charge voltages from 3.5 V to 4.44 V. Housed in a VQFN-14 surface-mount package, it functions across a temperature range of -40°C to +85°C.

Battery Chargers Feature Summary

Fully integrated switch-mode architecture for efficient charging
Supports lithium-ion and lithium-polymer battery chemistries
Compact VQFN-14 surface-mount packaging

Battery Chargers Applications

Single-cell lithium-ion battery charging systems
Lithium-polymer battery management applications
Portable electronic devices requiring compact power solutions

Battery Chargers Procurement Notes

Verify the specific suffix RGYR against the manufacturer datasheet to confirm package type and tape/reel specifications. Ensure compatibility with system input voltage limits between 4 V and 6 V. Confirm thermal requirements align with the specified operating temperature range of -40°C to +85°C before integration.

Battery Chargers Selection Notes

Select this component for applications requiring a single-cell solution with an input voltage ceiling of 6 V. The 1.2 A output current suits low-to-medium capacity batteries. Consider the VQFN-14 footprint for board space constraints compared to larger packages used in higher-power variants.

Battery Chargers Part Context

This part belongs to the BQ24155 series of battery chargers. It is distinct from other family members like the BQ24153 or BQ24157 due to its specific package configuration and electrical parameters. It serves as a specialized solution for single-cell charging within the broader Texas Instruments power management portfolio.

Battery Chargers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify cross-compatibility with similar models such as BQ24153 or BQ24157 only if datasheet parameters match exactly.
