BQ20Z65DBT-R1

Battery Management Overview

The BQ20Z65DBT-R1 is a System Battery Specification (SBS) 1.1 compliant gas gauge manufactured by Texas Instruments. It utilizes Impedance Track technology for accurate state-of-charge estimation and includes integrated protection features. The device operates within an ambient temperature range of -40°C to +85°C and is housed in a 44-pin Thin Shrink Small Outline Package (TSSOP).

Battery Management Feature Summary

• Complies with SBS 1.1 specifications for battery communication.
• Integrates Impedance Track technology for precise fuel gauging.
• Provides comprehensive cell and system protection mechanisms.

Battery Management Applications

• Portable computing devices
• Medical equipment
• Industrial instrumentation

Battery Management Procurement Notes

Verify the specific package variant, as the DBTR suffix typically indicates tape-and-reel packaging while DBT denotes tubes. Confirm the operating temperature grade matches the application requirements. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability.

Battery Management Selection Notes

Select this component when SBS 1.1 compliance is mandatory for host integration. It is suitable for applications requiring robust protection alongside accurate remaining capacity data. Consider the 44-pin TSSOP footprint during PCB layout planning.

Battery Management Part Context

This part belongs to the BQ20Z65 family of gas gauges. It shares core functionality with variants like the BQ20Z655 but may differ in packaging or revision status. The series is designed for single-cell lithium-ion and lithium-polymer battery management.

Battery Management Replacement Considerations

The BQ20Z655 is a functionally similar alternative within the same family. Verify pinout compatibility and software configuration before substitution.
