UC3906DWG4

Overview

The UC3906DWG4 is a lead-acid linear charge management integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of up to 40 V and delivers an output current of 2 A. The device is housed in a 16-pin SOIC package designed for surface-mount installation. It functions across a temperature range from -20 °C to +70 °C.

Feature Summary

• Linear charge management architecture optimized for lead-acid battery systems
• Integrated protection mechanisms against reverse polarity and overvoltage conditions

Applications

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

Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance status through official manufacturer documentation before procurement. Confirm that the SOIC-16 package dimensions align with your printed circuit board layout requirements. Ensure the operating temperature range meets your environmental specifications.

Selection Notes

Select this component when designing lead-acid battery chargers requiring linear regulation. Consider the 2 A output capability and 40 V input limit during system design. Evaluate thermal dissipation needs due to the linear topology. Verify compatibility with existing lead-acid battery chemistries supported by the internal control logic.

Part Context

This part belongs to the UC3906 series of battery management ICs. It shares functional similarities with other members like the UC3906NG4, differing primarily in packaging type. The series targets robust lead-acid charging solutions with integrated safety features.

Replacement Considerations

The UC3906DW is a non-RoHS variant of the same functional device. Verify regulatory requirements before substitution.
