BQ28Z610DRZT

Battery Management Overview

The BQ28Z610DRZT is a highly integrated, accurate gas gauge and protection solution for 1-series to 2-series Lithium-ion and Lithium Polymer batteries. It supports a maximum output voltage of 26 V with an output current capability of 20 mA. The device operates on a supply voltage ranging from 2.2 V to 26 V and draws a working supply current of 250 uA. It is housed in a SON-12 package designed for SMD/SMT installation. The component functions within a temperature range of -40 C to +85 C.

Battery Management Feature Summary

• Enables autonomous charger control through Master Mode I2C broadcasts of charging current and voltage information.
• Provides cell balancing capabilities for multi-cell battery configurations.
• Integrates safety features including overcurrent discharge, short circuit protection, and internal AFE watchdog.
• Combines a low-power RISC CPU with high-precision analog measurement and flash memory.

Battery Management Applications

• Lithium-ion battery pack management
• Lithium Polymer battery fuel gauging
• Autonomous charger control systems
• Cell balancing applications

Battery Management Procurement Notes

Verify the specific suffix DRZT against the manufacturer's official documentation to confirm the tape and reel packaging configuration. Ensure compatibility with the required operating voltage range and battery chemistry type before integration. Confirm that the SON-12 package dimensions align with the target PCB layout constraints.

Battery Management Selection Notes

Select this component for applications requiring precise state-of-charge monitoring in single or dual-series lithium battery systems. The integrated protection and balancing features reduce external component count. Consider the low standby current for power-sensitive designs. Validate firmware requirements for the custom instruction set if advanced customization is needed.

Battery Management Part Context

This part belongs to the BQ28Z610 series of battery management ICs from Texas Instruments. It is designed as a complete solution combining fuel gauging, protection, and communication interfaces. The device utilizes Impedance Track technology for accurate capacity estimation and includes security features such as SHA-2 authentication.

Battery Management Replacement Considerations

The BQ28Z610DRZR is a verified alternative offering identical electrical specifications but packaged in a Tape & Reel format instead of Cut Tape. Both variants share the same SON-12 footprint and functional capabilities.
