UCC3952AGSH-1

Overview

The UCC3952AGSH-1 is a single-cell lithium-ion battery protection integrated circuit manufactured by Texas Instruments. It provides comprehensive protection against overcharge, overdischarge, and overcurrent conditions to ensure safe operation of lithium-ion cells. The device operates within an ambient temperature range of -20°C to +70°C and utilizes a WFLGA-18 surface-mount package for compact board integration.

Feature Summary

• Integrated protection against overcharge, overdischarge, and overcurrent events
• Designed specifically for single-cell lithium-ion battery chemistries
• Surface-mount packaging optimized for space-constrained applications

Applications

• Single-cell lithium-ion battery pack protection
• Portable electronic device power management
• Consumer electronics with lithium-ion power sources

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm package integrity and moisture sensitivity levels prior to assembly. Ensure compliance with RoHS directives and check for obsolescence status before finalizing procurement plans.

Selection Notes

Select this component exclusively for single-cell lithium-ion configurations. Do not apply to multi-cell series arrangements such as 4S packs, as the device lacks necessary balancing or high-voltage handling capabilities. Validate thermal performance within the specified -20°C to +70°C operating range for target application environments.

Part Context

This part belongs to the UCC3952 family of battery protection ICs from Texas Instruments. It serves as a specialized solution for safeguarding individual lithium-ion cells in portable devices. The AGSH-1 variant denotes specific pinout and packaging characteristics distinct from other family members like the PWTR-2.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Verify functional compatibility with existing designs if considering alternatives, ensuring voltage thresholds and package dimensions match requirements.
