UCC3952DP-4

Overview

The UCC3952DP-4 is a single-cell lithium-ion battery protection integrated circuit manufactured by Texas Instruments. It provides comprehensive fault protection including overcurrent, overtemperature, overvoltage, undervoltage, and short-circuit conditions. The device operates within a temperature range of -20°C to +70°C (TA). It is housed in a 16-SOIC package with a width of 3.90mm. The component is RoHS3 compliant and classified under EAR99.

Feature Summary

• Integrated protection against overcurrent, overtemperature, overvoltage, undervoltage, and short circuits for single-cell lithium-ion batteries.

Applications

• Single-cell lithium-ion battery protection systems

Procurement Notes

Verify the obsolete status of this component before design finalization. Confirm availability through authorized distributors or secondary market suppliers like Rochester Electronics. Ensure the 16-SOIC package dimensions match the PCB footprint requirements. Check for RoHS3 compliance documentation if required by specific regional regulations.

Selection Notes

Select this part for applications requiring integrated protection for single-cell lithium-ion batteries. Consider the -20°C to +70°C operating temperature range suitability. Evaluate the 16-SOIC package constraints against available board space. Note that the component is discontinued, which may impact long-term supply stability.

Part Context

The UCC3952 series includes variants such as UCC3952PWTR-2 and UCC3952PW-4G4. These share similar battery management functions but differ in packaging and suffix codes. The DP-4 variant specifically denotes the SOIC package configuration. Other family members include TSSOP options like the PW series.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source data. Due to the discontinued status, alternative sourcing should be verified carefully. No direct equivalent replacements are listed in the provided documentation.
