BQ27500DRZR-V130

Battery Management Overview

The BQ27500DRZR-V130 is a System-Side Impedance Track fuel gauge IC from Texas Instruments, designed for single-cell lithium-ion and lithium-polymer battery packs. It operates within a supply voltage range of 2.5 V to 5.5 V and supports battery capacities between 300 mAh and 8000 mAh. The device functions as a microcontroller peripheral, utilizing the patented Impedance Track algorithm to monitor remaining capacity, state of charge, and runtime. It features an I²C interface for system communication and includes an internal temperature sensor. The component is housed in a 12-pin SON package with dimensions of 4.15 mm x 2.6 mm x 0.95 mm.

Battery Management Feature Summary

• System-side placement on the mainboard manages both embedded and removable battery packs
• Patented Impedance Track technology models discharge curves for accurate runtime prediction
• Automatic compensation for battery aging, self-discharge, and rate/temperature inefficiencies
• Integrated low-value sense resistor support (10 mΩ or less) simplifies hardware design

Battery Management Applications

Battery Management Procurement Notes

Verify the specific suffix V130 against current manufacturer documentation to confirm firmware version and availability status. Cross-reference the part number with official Texas Instruments databases to ensure compliance with RoHS standards and check for any process change notifications that may affect performance characteristics or pin compatibility.

Battery Management Selection Notes

Select this component when system-side fuel gauging is required for single-cell lithium-based batteries. It is suitable for applications where the battery management circuit resides on the host motherboard rather than the pack itself. Ensure the system microcontroller supports I²C communication and that the battery capacity falls within the supported 300 mAh to 8000 mAh range for optimal algorithm performance.
