LV51134T-TLM-E

Overview

The LV51134T-TLM-E is a battery protection IC designed for lithium-ion and lithium-polymer batteries. It integrates high-voltage MOSFETs to provide comprehensive protection against overcharge, overdischarge, overcurrent, and short-circuit conditions. The device features an I2C interface for system control and monitoring, allowing for flexible configuration of protection thresholds and timing parameters. Packaged in an 8-MSOP format, it supports dual-cell configurations with low on-resistance switches to minimize power loss during operation.

Feature Summary

• Integrated high-voltage N-channel MOSFETs for efficient power switching
• I2C interface enables digital control and real-time status monitoring
• Comprehensive protection against electrical faults including overvoltage and short circuits

Applications

• Lithium-ion battery packs for portable electronics
• Power tool battery management systems
• Uninterruptible power supply (UPS) units

Procurement Notes

Verify the specific suffix TLM-E matches the required tape-and-reel packaging quantity and lead time requirements. Confirm that the manufacturer has not discontinued this part number or replaced it with a newer revision. Ensure the ordering information aligns with the intended volume and delivery schedule before finalizing procurement.

Selection Notes

Select this component when a compact solution for dual-cell lithium battery protection is required. The integrated I2C interface offers advantages for systems needing programmable protection settings. Consider the thermal performance and package size constraints relative to the expected current loads in the target application design.

Part Context

This component belongs to Sanyo's (now Panasonic) line of battery protection ICs. These devices are engineered to ensure safety and longevity in rechargeable battery applications. The LV51134 series specifically targets applications requiring robust fault protection within a small footprint, commonly found in consumer electronics and industrial equipment.
