UCC3957MTR-1

Battery Management Overview

The UCC3957MTR-1 is a BiCMOS three- or four-cell lithium-ion battery pack protector designed to operate with external P-channel MOSFETs. It provides comprehensive protection against overvoltage, undervoltage, and overcurrent conditions. The device integrates precise voltage references and comparators to monitor cell voltages and total pack voltage. It supports series configurations for high-voltage battery packs. The component is housed in a 16-pin SSOP package.

Battery Management Feature Summary

• Integrates precision voltage monitoring for individual cells and the total battery pack
• Provides fault protection including overvoltage, undervoltage, and overcurrent detection
• Designed to interface directly with external P-channel MOSFETs for power switching
• Supports configuration for both three-cell and four-cell lithium-ion battery architectures

Battery Management Applications

• Lithium-ion battery pack protection in portable electronic devices
• Power management systems for cordless tools
• Uninterruptible power supply (UPS) battery modules
• Medical equipment requiring reliable lithium-ion battery safety

Battery Management Procurement Notes

Verify the specific suffix MTR-1 indicates the tape and reel packaging variant. Confirm the manufacturer is Texas Instruments. Ensure the part number matches the exact pinout and electrical specifications required for your design. Cross-reference with official datasheets to validate compatibility with your chosen external MOSFETs.

Battery Management Selection Notes

Select this component when designing protection circuits for three or four-series lithium-ion cells. Ensure the external P-channel MOSFETs selected can handle the expected load current and voltage ratings. Verify that the operating temperature range meets the application requirements. Consider the SSOP package size constraints during PCB layout planning.

Battery Management Part Context

The UCC3957 belongs to Texas Instruments' family of battery protection ICs. It is specifically engineered for multi-cell lithium-ion applications where precise monitoring and robust fault protection are critical. The device simplifies battery management by integrating multiple protection functions into a single compact solution.

Battery Management Replacement Considerations

Check for direct substitutes within the UCC395x family. Verify pin-to-pin compatibility if replacing with other TI battery protectors. Ensure any alternative component supports the same cell count and external MOSFET interface requirements.
