UCC3952DP-1

Overview

The UCC3952DP-1 is a single-cell lithium-ion battery protection integrated circuit manufactured by Texas Instruments. It is housed in a 16-SOIC surface-mount package with a width of 0.154 inches (3.90 mm). The device operates within a temperature range of -20°C to +70°C. It provides comprehensive fault protection including overcurrent, overtemperature, overvoltage, undervoltage, and short-circuit conditions. The component is RoHS compliant and classified under EAR99 export control.

Feature Summary

• Integrated protection against overcurrent, overtemperature, overvoltage, undervoltage, and short circuits for single-cell lithium-ion batteries
• Surface-mount design in a compact 16-SOIC package for efficient PCB integration
• Operates reliably across an extended industrial temperature range from -20°C to +70°C

Applications

• Single-cell lithium-ion battery pack protection
• Portable electronic devices requiring cell-level safety monitoring
• Industrial equipment utilizing lithium-ion power sources

Procurement Notes

Verify the specific suffix designation when sourcing, as variants such as UCC3952DP-3G4 or UCC3952DP-4 exist within the same family. Confirm current availability status as some listings indicate discontinued status or limited supply through secondary distributors. Ensure the selected part matches the required package type and thermal specifications for the target application environment.

Selection Notes

Select this component for applications requiring robust, integrated protection for single-cell lithium-ion systems. The 16-SOIC package offers compatibility with standard surface-mount assembly processes. Consider the operating temperature range and fault protection features when evaluating suitability for harsh environments or high-reliability portable electronics.

Part Context

The UCC3952 series comprises battery protection ICs designed for lithium-ion cells. The UCC3952DP-1 variant specifically targets single-cell applications. It belongs to the Power Management IC category, focusing on safety and longevity of energy storage components. The device integrates multiple protection functions into a single compact solution, reducing external component count.

Replacement Considerations

Direct substitutes include other UCC3952 variants like UCC3952DP-3G4 or UCC3952PWTR-2, provided pinout and functional requirements match. Verify package compatibility between SOIC and TSSOP options if space constraints differ. Cross-reference datasheets to ensure identical fault thresholds and operating temperatures before substitution.
