Overview
The UCC3957MTR-3 is a battery protection integrated circuit designed for three to four-cell lithium-ion battery packs. Manufactured by Texas Instruments, this component operates within a temperature range of -20°C to 70°C and utilizes a 16-pin SSOP surface-mount package. It provides essential fault protection mechanisms to ensure battery safety during operation.
Feature Summary
- Provides comprehensive protection for multi-cell lithium-ion battery configurations
- Integrates fault detection capabilities to safeguard against operational anomalies
- Designed for surface-mount assembly in compact electronic devices
Applications
- Lithium-ion battery pack protection systems
- Portable electronic device power management
- Consumer electronics with multi-cell battery requirements
Procurement Notes
Verify the specific suffix 'MTR-3' corresponds to the required tape-and-reel packaging format and voltage threshold configuration. Confirm that the 16-SSOP package dimensions match your PCB footprint design. Ensure compatibility with the target operating temperature range of -20°C to 70°C for your specific application environment before finalizing procurement.
Selection Notes
Select this component when protecting three or four series-connected lithium-ion cells requiring integrated fault monitoring. The choice depends on the need for a single-chip solution that combines protection logic with a compact surface-mount form factor. Consider the thermal performance limits and pinout compatibility with existing board layouts during the selection process.
Part Context
This part belongs to the UCC3957 family of lithium-ion protectors from Texas Instruments. Variants such as UCC3957M-4 and UCC3957MTR-2 share similar functional descriptions but may differ in specific voltage thresholds or packaging options. The family addresses safety requirements for portable energy storage applications.
Replacement Considerations
Direct substitutes include other parts in the UCC3957 series like UCC3957MTR-4, provided the cell count and voltage thresholds align. Cross-reference pinouts and electrical specifications carefully to ensure functional equivalence without redesigning the host circuit.
