UC2909DWTRG4

Overview

The UC2909DWTRG4 is a switchmode lead-acid battery charger 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 with a maximum output voltage of 20 V. The device is housed in a 20-pin SOIC package designed for surface-mount technology. It supports an extended operating temperature range from -55 °C to +125 °C, ensuring reliability in demanding environments.

Feature Summary

Implements switchmode charging architecture optimized for lead-acid battery chemistries
Provides programmable charge current control capabilities
Integrates comprehensive fault protection mechanisms for system safety

Applications

Lead-acid battery management systems
Uninterruptible power supply (UPS) units
Solar energy storage controllers

Procurement Notes

Verify the specific suffix 'G4' indicates RoHS compliance and green material status as per Texas Instruments documentation. Confirm the SOIC-20 package dimensions match your PCB footprint requirements. Ensure the -55 °C to +125 °C temperature rating aligns with your operational environment specifications before finalizing procurement.

Selection Notes

Select this component when designing lead-acid charging solutions requiring high-temperature resilience and switchmode efficiency. The 2 A output current capability suits moderate-capacity battery banks. Consider the 20-pin SOIC package for surface-mount assembly constraints. Verify that the 40 V maximum supply voltage accommodates your input power stage design.

Part Context

This part belongs to the UC2909 series of switchmode lead-acid battery chargers from Texas Instruments. The 'DWTRG4' designation specifies the tape-and-reel packaging format, the SOIC-20 package type, and RoHS-compliant manufacturing. It serves as a specialized power management IC for dedicated battery charging applications.
