UCC3952PW-1

Overview

The UCC3952PW-1 is an enhanced single-cell lithium-ion battery protection integrated circuit manufactured by Texas Instruments. Designed for portable applications, it provides comprehensive cell protection against overcharge, overdischarge, and short-circuit conditions. The device integrates a precision voltage reference and comparator logic to monitor cell voltage and current. It operates within a specified temperature range and utilizes a TSSOP-16 surface-mount package for compact board integration.

Feature Summary

• Integrated overcharge protection with programmable threshold monitoring
• Overdischarge protection mechanism to prevent cell damage
• Short-circuit protection for fault isolation
• Single-cell lithium-ion chemistry compatibility

Applications

• Portable electronic devices requiring single-cell battery management
• Lithium-ion battery pack protection circuits
• Consumer electronics with integrated power management needs

Procurement Notes

Verify the specific suffix variant (e.g., PW-1 vs PW-2) as different suffixes may indicate distinct electrical characteristics or packaging options. Confirm availability status through authorized distributors, as lifecycle status may vary. Ensure component authenticity by sourcing from TI-authorized channels to guarantee performance reliability and compliance with specifications.

Selection Notes

Select this component for designs requiring a dedicated single-cell lithium-ion protection solution. Evaluate the TSSOP-16 package constraints against PCB layout requirements. Consider the operating temperature range relative to the target application environment. Verify that the integrated protection thresholds align with the specific lithium-ion cell chemistry being protected.
