BQ2004ESNTR

Battery Chargers Overview

The BQ2004ESNTR is a multi-chemistry battery control IC manufactured by Texas Instruments, designed for managing rechargeable battery packs. It supports constant current and pulse charging profiles with programmable voltage parameters. The device operates within a supply voltage range of up to 5.5V and functions reliably across an industrial temperature range of -20°C to +70°C. Packaged in a 16-SOIC surface-mount format with a width of 3.90mm, it integrates essential battery management functions into a compact form factor suitable for portable electronics.

Battery Chargers Feature Summary

• Supports multi-chemistry battery types including lithium-ion and nickel-based cells
• Enables programmable voltage regulation for precise charge control
• Facilitates both constant current and pulse charging methodologies

Battery Chargers Applications

• Portable consumer electronics requiring multi-chemistry battery support
• Battery-powered devices utilizing pulse charging techniques
• Industrial equipment operating within specified temperature ranges

Battery Chargers Procurement Notes

Verify the specific suffix 'SNTR' corresponds to the tape-and-reel packaging configuration when ordering. Confirm that the component meets RoHS3 compliance standards as indicated in official documentation. Ensure compatibility with the 16-SOIC footprint during PCB layout. Cross-reference the manufacturer part number against distributor catalogs to avoid confusion with similar variants in the BQ2004 family.

Battery Chargers Selection Notes

Select this component when multi-chemistry flexibility is required alongside programmable voltage control. Consider the 16-SOIC package constraints for board space limitations. Evaluate the -20°C to +70°C operating range against environmental conditions. Verify that the 5.5V maximum supply voltage aligns with system power architecture requirements before integration.

Battery Chargers Part Context

This part belongs to the BQ2004 series of battery management integrated circuits from Texas Instruments. The series provides comprehensive solutions for monitoring and controlling various battery chemistries. The ESNTR variant specifically denotes the surface-mount package and reel packaging style, distinguishing it from through-hole or tray options within the same functional family.

Battery Chargers Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the BQ2004HSN, BQ2004HSNTR, and BQ2004SN. These alternatives share similar functional characteristics but may differ in packaging or specific electrical tolerances. Verify pinout compatibility and thermal performance before substituting.
