BQ24740RHDRG4

Battery Chargers Overview

The BQ24740RHDRG4 is a host-controlled, multi-chemistry battery charger IC designed for two, three, or four series lithium-ion cells. It supports up to 10 A of charge current and operates within a 28-V input range. The device integrates synchronous switching regulation for high efficiency. Key electrical parameters include a maximum charge current of 10 A and an operating voltage range extending to 28 V. It is housed in a 28-pin, 5x5-mm thin QFN package suitable for space-constrained applications.

Battery Chargers Feature Summary

• Host-controlled architecture enabling system-level management of charging profiles
• Integrated synchronous buck converter for efficient power conversion
• Supports multiple cell configurations including two, three, or four series cells
• Built-in input over-voltage protection to safeguard the supply source

Battery Chargers Applications

• Portable computing devices requiring multi-cell battery packs
• Industrial equipment with high-current charging requirements
• Medical devices needing reliable multi-chemistry battery support
• Uninterruptible power supplies (UPS) systems

Battery Chargers Procurement Notes

Verify the specific suffix 'G4' indicates lead-free and RoHS compliance status according to Texas Instruments documentation. Confirm the package type matches the 28-pin 5x5-mm thin QFN specification. Ensure the host controller interface compatibility aligns with your system design before procurement.

Battery Chargers Selection Notes

Select this component when a host processor manages the charging algorithm rather than autonomous control. It is suitable for applications requiring high charge currents up to 10 A. Consider the thermal performance of the thin QFN package in your layout. Verify that the input voltage does not exceed the 28-V limit under all operating conditions.

Battery Chargers Part Context

This part belongs to the BQ24740 family of battery chargers from Texas Instruments. It is designed for applications where the main processor handles charging decisions. The RHDRG4 designation specifies the package style and environmental compliance. It serves as a solution for complex battery management in portable and industrial electronics.

Battery Chargers Replacement Considerations

Check for direct pin-to-pin replacements within the BQ24740 series. Verify if alternative TI models offer similar host-control interfaces. Ensure any substitute supports the required number of series cells and current ratings.
