UC3906QTR

Battery Chargers Overview

The UC3906QTR is a lead-acid battery charge management integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of up to 40 V and supports a maximum output current of 2 A. The component is housed in a 20-PLCC package with dimensions of 9x9 mm. It functions across an operating temperature range from -20 °C to +70 °C. This device is designed for linear charge management applications specifically tailored for lead-acid battery systems.

Battery Chargers Feature Summary

• Integrated linear charge management controller optimized for lead-acid battery chemistries
• Supports high current charging capabilities up to 2 A output
• Operates reliably within extended industrial temperature ranges

Battery Chargers Applications

• Lead-acid battery charging systems
• Uninterruptible power supply (UPS) battery management
• Solar energy storage battery regulation

Battery Chargers Procurement Notes

Verify the specific package variant, as the UC3906 series includes SOIC, PDIP, and PLCC options. Confirm that the QTR suffix corresponds to the 20-PLCC tape and reel format required for your assembly process. Ensure compatibility with the target lead-acid battery voltage and current specifications before procurement.

Battery Chargers Selection Notes

Select this component when designing for lead-acid batteries requiring linear charge control. Compare against UC3906DWG4 or UC3906NG4 if surface-mount or through-hole packaging preferences differ. Verify that the 2 A output capability meets the system's charging requirements and that the 40 V input limit aligns with the source voltage.

Battery Chargers Part Context

The UC3906 belongs to Texas Instruments' specialized power management family focused on battery charging. It complements other devices like the UC3907 load share controller. The QTR designation indicates a specific tape-and-reel packaging configuration within the broader UC3906 product line, distinguishing it from tube-packaged variants.

Battery Chargers Replacement Considerations

UC3906Q is a direct equivalent part number. UC3906DWG4 and UC3906NG4 are alternative packages within the same functional family but require mechanical adaptation.
