LV51130T-TLM-E

Overview

The LV51130T-TLM-E is a battery protection IC designed for two-cell lithium-ion secondary batteries. It integrates over-current, short-circuit, and over-voltage/under-voltage protection functions to ensure safe operation. The device operates within an input voltage range of 8 V to 42 V and supports a switching frequency of 300 kHz. It delivers an output current of 5 mA through a single output channel. The component is housed in an MSOP-12 package and is rated for industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Integrated protection against over-current, short-circuit, and voltage anomalies for dual-cell lithium-ion systems
• Compact surface-mount packaging suitable for space-constrained portable electronics
• Designed for reliable operation across extended industrial temperature environments

Applications

• Two-cell lithium-ion battery packs
• Portable electronic devices requiring integrated cell protection

Procurement Notes

Verify the specific ordering suffix and RoHS compliance status directly with onsemi or authorized distributors before procurement. Confirm that the MSOP-12 package variant matches your PCB footprint requirements. Check for any recent product change notices (PCNs) regarding manufacturing site transfers or material updates. Ensure the component meets all relevant safety standards for your target market. Validate lead times as availability may vary by region.

Selection Notes

Select this component when designing circuits requiring dedicated protection for two-series lithium-ion cells. Ensure the input voltage range aligns with your system's maximum operating conditions. Consider the thermal performance of the MSOP-12 package under expected load currents. Verify compatibility with your board layout constraints due to the small form factor. Evaluate if the integrated fault protection features meet your safety certification requirements.
