BQ7693003DBTR

Battery Management Overview

The BQ7693003DBTR is a battery management analog front-end device from Texas Instruments, designed for monitoring and protecting lithium-ion and lithium iron phosphate battery packs. It supports configurations of 6 to 10 series cells with a maximum operating supply voltage of 25 V. The device features an integrated 3.3 V output regulator and operates within a temperature range of -40°C to +85°C. Packaged in a TSSOP-30 surface-mount format, it draws a typical operating supply current of 40 µA. This component serves as part of a complete pack monitoring solution for high-power systems.

Battery Management Feature Summary

• Supports battery chemistries including Lithium-ion, Lithium Polymer, and Lithium Iron Phosphate (LiFePO4).
• Enables ultra-low power consumption through sub-block enable/disable controls and SHIP mode.
• Provides robust protection capabilities suitable for next-generation high-power applications.

Battery Management Applications

• Light electric vehicles
• Power tools
• Uninterruptible power supplies

Battery Management Procurement Notes

Verify the specific package variant when ordering, as the BQ7693003DBT designation indicates tube packaging while the 'R' suffix denotes reel packaging. Confirm that the required quantity aligns with the manufacturer's standard factory pack sizes. Ensure compatibility with the target system's voltage requirements and thermal environment before finalizing procurement decisions.

Battery Management Selection Notes

Select this component for applications requiring dedicated monitoring of 6 to 10-series cell packs. It is appropriate for designs prioritizing low quiescent current and support for multiple lithium-based chemistries. Consider the TSSOP-30 footprint constraints and the need for external protection circuitry to complement the internal AFE functions.

Battery Management Part Context

This part belongs to the BQ769x0 family of analog front-end devices manufactured by Texas Instruments. These components are engineered to provide comprehensive battery pack monitoring and protection. The family is characterized by low power design principles and flexible configuration options for various high-power energy storage and delivery systems.

Battery Management Replacement Considerations

The BQ7693003DBT is a verified substitute part number offering identical electrical specifications but differing only in packaging format. Verify that the application board layout accommodates the tube package dimensions if switching from the reel version.
