BQ20Z60DBT-R1

Battery Management Overview

The BQ20Z60DBT-R1 is a Smart Battery System (SBS) 1.1 compliant gas gauge manufactured by Texas Instruments. It utilizes Impedance Track technology for accurate state-of-charge estimation in lithium-ion and lithium-polymer battery packs. The device operates within a supply voltage range of 4.5 V to 25 V and supports an output current capability of 1 mA. It is housed in a 38-pin Thin Shrink Small Outline Package (TSSOP). The component is designed for operation across an industrial temperature range from -40°C to +85°C.

Battery Management Feature Summary

• Impedance Track technology enables precise state-of-charge calculation through dynamic battery modeling.
• Compliance with SBS 1.1 standards ensures interoperability with host systems and chargers.
• Integrated protection features monitor cell overvoltage, undervoltage, and overcurrent conditions.

Battery Management Applications

• Laptop computers
• Portable medical devices
• Industrial handheld equipment

Battery Management Procurement Notes

Verify the specific revision suffix (R1) against the manufacturer's latest documentation to ensure compatibility with required firmware or hardware configurations. Confirm that the 38-pin TSSOP package dimensions align with the target PCB layout. Check for any end-of-life notifications or recommended new designations before finalizing procurement plans.

Battery Management Selection Notes

Select this component when SBS 1.1 compliance is mandatory for system integration. Ensure the application requires support for single-cell lithium-ion or polymer chemistries within the specified voltage window. Verify that the thermal environment remains within the -40°C to +85°C operational limits during all phases of use.

Battery Management Part Context

This part belongs to the BQ20Z series of fuel gauges, which are designed for portable electronics requiring high accuracy. The BQ20Z60 variant specifically targets applications needing robust state-of-charge tracking without external memory for battery data.

Battery Management Replacement Considerations

Consult official change lists for updates within the BQ20Z family. Verify pinout and functional equivalence before substituting with other Texas Instruments gas gauge models.
