BQ25173DSGR

Battery Chargers Overview

The BQ25173DSGR is a linear charge management IC from Texas Instruments designed for supercapacitor applications. It supports charging configurations for one to four cells in series. The device operates with an input voltage range of 3 V to 18 V and delivers a maximum output current of 800 mA. It provides regulated output voltages up to 10.5 V. The component is housed in an 8-pin WSON package and is rated for operation at temperatures up to +125°C.

Battery Chargers Feature Summary

• Linear charging architecture optimized for supercapacitor energy storage systems
• Supports multi-cell series configurations ranging from single to four cells
• Integrated thermal regulation to manage power dissipation during charging cycles

Battery Chargers Applications

• Supercapacitor bank charging in industrial equipment
• Energy harvesting system power management
• Backup power supply conditioning for capacitive storage

Battery Chargers Procurement Notes

Verify the specific suffix 'DSGR' against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration and temperature grade. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target circuit design before finalizing procurement.

Battery Chargers Selection Notes

Select this component when designing circuits that require precise linear charging control for supercapacitors rather than lithium-ion batteries. Consider the thermal performance requirements associated with the WSON-8 package, as linear regulators dissipate excess voltage as heat. Verify that the application input voltage remains within the specified 3 V to 18 V operational range.

Battery Chargers Part Context

This part belongs to the BQ25173 family of battery management solutions from Texas Instruments. The family focuses on low-component-count solutions for energy storage devices. The DSGR variant specifically denotes the surface-mount reel packaging format suitable for automated assembly processes in high-volume manufacturing environments.

Battery Chargers Replacement Considerations

Consult the Texas Instruments product transition notification (PCN) for any obsolescence notices. Direct functional equivalents may exist within the same BQ2517x series, but pin compatibility and thermal characteristics must be verified against official substitution lists.
