• Integrated overvoltage and undervoltage protection mechanisms
• Overcurrent and short-circuit fault detection capabilities
• Precision monitoring of single-cell lithium-ion battery parameters

Applications

• Single-cell lithium-ion battery protection in portable devices
• Power management systems requiring cell-level safety monitoring
• Consumer electronics with integrated battery packs

Procurement Notes

Verify the exact suffix DP-1 corresponds to the specific package variant required. Confirm active status through official TI channels as product lifecycles may change. Ensure compatibility with existing PCB footprint and thermal requirements before finalizing procurement decisions based on verified datasheet specifications.

Selection Notes

Select this component when single-cell lithium-ion protection is required with integrated fault handling. Consider the package type and operating temperature range relative to the application environment. Verify that the protection thresholds align with the specific battery chemistry and system voltage requirements defined in the technical documentation.

Part Context

This part belongs to the UCC3958 family of battery protection ICs from Texas Instruments. The family includes variants such as UCC3958-1 and UCC3958-2, which offer similar protection functionalities for single-cell applications. These devices are designed to replace discrete protection solutions by integrating multiple safety features into a compact form factor suitable for space-constrained designs.

Replacement Considerations

Official substitutes include other members of the UCC3958 family such as UCC3958-1 or UCC3958-2, provided pinout and functional compatibility are confirmed. Cross-reference with equivalent single-cell Li-ion protection ICs from other manufacturers only if electrical characteristics and package dimensions match exactly.
