Battery Chargers datasheet and documents for BQ24123RHLR

BQ24123RHLR

Battery Chargers Overview

The BQ24123RHLR is a single-chip switched-mode Li-Ion and Li-Polymer charge-management IC from Texas Instruments. It supports one to three series cells with a maximum charge current of 2 A. The device operates within an input voltage range of 4.35 V to 16 V, featuring integrated power FETs and enhanced EMI performance. It utilizes a synchronous buck topology for efficient charging.

Battery Chargers Feature Summary

Integrated synchronous buck converter with internal power FETs
Enhanced electromagnetic interference (EMI) performance
Supports standalone configuration using RC-settable parameters

Battery Chargers Applications

Portable electronic devices requiring compact battery charging solutions
Consumer electronics utilizing multi-cell lithium-ion or polymer batteries
Industrial equipment with strict EMI requirements

Battery Chargers Procurement Notes

Verify the specific suffix RHLR against the manufacturer datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with the intended input voltage range and cell count configuration before procurement.

Battery Chargers Selection Notes

Select this component for applications requiring high efficiency in space-constrained designs. The integrated FETs reduce external component count. Verify thermal management requirements due to the synchronous buck architecture and ensure the input source meets the specified operating voltage limits.

Battery Chargers Part Context

This part belongs to the bqSWITCHER family of battery chargers. It shares architectural similarities with the BQ24120 and BQ24125 but is specifically optimized for one to three series cells. The family emphasizes compactness and EMI compliance for modern portable electronics.

Battery Chargers Replacement Considerations

The BQ24120RHLT serves as a compatible alternative for single-cell applications. The BQ24125RHLR offers similar features with enhanced EMI performance for multi-cell setups. Verify pinout and parameter settings when substituting.
