BQ27505YZGR-J3

Battery Management Overview

The BQ27505YZGR-J3 is a system-side Impedance Track fuel gauge from Texas Instruments, designed for single-cell lithium-ion or lithium polymer batteries. It operates within a temperature range of -40°C to +85°C and utilizes a DSBGA-12 package. The device supports I2C communication and is part of the BQ27505-J3 series.

Battery Management Feature Summary

• Implements the Impedance Track algorithm for accurate state-of-charge monitoring
• Provides system-side battery management capabilities
• Supports standard I2C interface for host communication

Battery Management Applications

• Single-cell portable electronic devices
• Lithium-ion battery pack monitoring systems
• Consumer electronics requiring precise fuel gauging

Battery Management Procurement Notes

Verify the specific revision suffix J3 against current datasheets, as newer revisions like J4 or J5 may be available. Confirm package type DSBGA-12 and operating temperature range match design requirements. Check for any pinout or functional changes in later revisions before finalizing procurement.

Battery Management Selection Notes

Select this component for applications requiring system-side fuel gauging with Impedance Track accuracy. Ensure compatibility with the target single-cell chemistry and I2C bus voltage levels. Consider availability of newer revisions if long-term supply is critical.

Battery Management Part Context

This component belongs to the BQ27505 family of fuel gauges. The J3 revision represents an earlier version of the Impedance Track fuel gauge. Later revisions such as J4 and J5 exist with potential updates to features or manufacturing processes.

Battery Management Replacement Considerations

Check for direct replacements like BQ27505YZGR-J4 or J5. Verify if pinouts and functionality remain identical across revisions to ensure drop-in compatibility without schematic changes.
