Overview
The UCC3952DP-3 is a single-cell Lithium-Ion battery protection integrated circuit manufactured by Texas Instruments. It features an internal power FET and provides comprehensive protection against over-current, over-temperature, over-voltage, and under-voltage conditions. The device operates within a supply voltage range of 1.4V to 3.6V and supports an output current of 3A. It is housed in a 16-SOIC surface-mount package with an operating temperature range from -20°C to +70°C.
Feature Summary
- Integrates internal power FET for compact design
- Provides multi-fault protection including over-current and thermal shutdown
- Supports single-cell Lithium-Ion battery monitoring
Applications
- Single-cell Lithium-Ion battery pack protection
- Portable electronic devices requiring battery management
- Power tools with Li-ion batteries
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'DP-3' matches the required 16-SOIC package and 4.2V output variant. Check for moisture sensitivity handling requirements during storage and assembly. Ensure compatibility with existing PCB footprint and thermal management strategies.
Selection Notes
Select this IC for applications requiring integrated protection for single-cell Lithium-Ion batteries. The internal FET reduces external component count compared to discrete solutions. Verify that the 3A current rating meets the system's peak load requirements. Consider the 16-SOIC package size constraints and thermal dissipation capabilities within the final enclosure design.
Part Context
This component belongs to the UCC3952 family of battery protection ICs from Texas Instruments. Variants such as UCC3952PWTR-2 and UCC3952DP-3G4 share similar functionality but may differ in packaging or specific electrical characteristics. The DP-3 variant specifically denotes the SOIC package configuration.
Replacement Considerations
Direct substitutes include other UCC3952 variants like UCC3952DP-3G4 if pin-compatible. Cross-reference with UCC3952PWTR-2 only if TSSOP-16 packaging is acceptable. Verify equivalent fault protection thresholds and internal FET specifications before substitution.
