BQ2050HSN-A508TRG4

Battery Management Overview

The BQ2050HSN-A508TRG4 is a Li-Ion gas gauge featuring a high-speed 1-Wire (HDQ) interface and five LED drivers. It operates within a supply voltage range of 3 V to 6.5 V, with a nominal voltage of 4.25 V. The device supports battery capacities between 500 mAh and 6000 mAh. It functions in an operating temperature range of 0°C to 70°C and utilizes a 16-pin SOIC package.

Battery Management Feature Summary

• Integrates a high-speed 1-Wire (HDQ) communication interface for data exchange.
• Includes built-in drivers for five LEDs to indicate battery status.
• Designed specifically for lithium-ion and lithium-polymer battery management.

Battery Management Applications

• Lithium-ion battery pack monitoring
• Lithium-polymer battery system management
• Portable electronic devices requiring fuel gauge functionality

Battery Management Procurement Notes

Verify the specific suffix 'A508' matches the required capacity configuration. Confirm the 'TRG4' designation indicates tape-and-reel packaging and RoHS compliance. Ensure the 16-SOIC package dimensions align with the target PCB layout. Check for any product discontinuation notices or lifecycle changes from Texas Instruments before finalizing procurement plans.

Battery Management Selection Notes

Select this component when a single-wire interface is required to minimize pin count. It is suitable for applications needing integrated LED indication without external drivers. Consider the 0°C to 70°C operating range against environmental requirements. Verify that the supported capacity range of 500 mAh to 6000 mAh meets the specific battery design needs.

Battery Management Part Context

This part belongs to the BQ2050H series of gas gauges from Texas Instruments. It shares core architecture with variants like the BQ2050HSN-A308 but differs in specific configuration parameters indicated by the suffix. The series provides a compact solution for battery state-of-charge estimation using the HDQ protocol.

Battery Management Replacement Considerations

The BQ2050HSN-A508TR is a related variant within the same family. Verify if the non-G4 suffix meets regulatory requirements. Cross-reference the A508 configuration code to ensure functional equivalence regarding capacity settings and LED driver behavior.
