BQ24751RHDT

Battery Chargers Overview

The BQ24751BRHDT is a host-controlled multi-chemistry battery charger IC from Texas Instruments, designed for systems requiring flexible battery management. It supports 2 to 4 series cells with a maximum battery pack voltage of 18.048V and a supply voltage up to 24V. The device delivers a programmable constant charging current up to 10A. It integrates an AC over-power protection feature to limit input power draw. The component operates within a junction temperature range of -40°C to 125°C and is housed in a 28-VQFN (5x5) package.

Battery Chargers Feature Summary

• Host-controlled architecture enabling system-level integration and monitoring
• Integrated AC over-power protection to manage input power limits
• Supports multiple battery chemistries including Li-ion and Li-polymer
• Programmable constant current charging capability

Battery Chargers Applications

• Portable medical devices
• Industrial handheld equipment
• Uninterruptible power supplies (UPS)
• Power tools

Battery Chargers Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with the target host controller interface. Confirm RoHS compliance status matches project requirements. Validate that the 28-VQFN footprint aligns with the PCB design. Check for any automotive or industrial qualification certifications if required by the application environment.

Battery Chargers Selection Notes

Select this component when a host processor manages the charging profile rather than standalone hardware control. It is suitable for applications requiring high input current handling up to 10A. Consider the integrated power path selector if system power distribution is needed. Verify that the operating voltage range covers the specific battery configuration used in the design.

Battery Chargers Part Context

This part belongs to the BQ24751 family of multi-chemistry chargers. Variants such as BQ24751ARHDR share similar functionalities but may differ in packaging or specific electrical characteristics. The BRHDT suffix indicates a specific reel quantity and package variant within the standard product line.

Battery Chargers Replacement Considerations

Official substitutes include BQ24751ARHDR and BQ24751B. Verify pinout compatibility and electrical parameters before substitution. Cross-reference datasheets to ensure equivalent performance in over-power protection and charging algorithms.
