LM5068MM-2/NOPB

Hot Swap Controllers Overview

The LM5068MM-2/NOPB is a single-channel negative voltage hot swap controller designed for -9 V to -90 V input supplies. It integrates an N-channel MOSFET driver with adjustable current limiting, programmable soft-start, and fault protection features including overvoltage protection (OVP) and undervoltage lockout (UVLO). The device supports automatic retry start-up cycles after fault conditions. It operates within a temperature range of -40°C to +105°C and is housed in an 8-pin VSSOP package.

Hot Swap Controllers Feature Summary

• Integrates automatic retry functionality for continuous operation after transient faults
• Provides comprehensive protection via programmable circuit breaker, OVP, and UVLO
• Supports precise load management through adjustable current limiting and soft-start

Hot Swap Controllers Applications

• Telecommunications equipment requiring safe insertion and removal under negative bias
• Industrial control systems utilizing -48 V power architectures
• Server backplanes needing protected power distribution for negative rail components

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free and RoHS compliance status as per the manufacturer's latest documentation. Confirm the '-2' designation aligns with the required automatic retry behavior for your system design. Ensure the VSSOP-8 package footprint matches your PCB layout constraints before finalizing procurement orders.

Hot Swap Controllers Selection Notes

Select this component when designing circuits that require protection for negative voltage rails between -9 V and -90 V. It is suitable for applications demanding integrated fault handling without external discrete protection components. Consider the 8-pin VSSOP package size if space-constrained layouts are necessary compared to larger SOIC packages.

Hot Swap Controllers Part Context

This part belongs to the LM5068 family of negative voltage hot swap controllers from Texas Instruments. It serves as a specialized power management IC for protecting downstream loads during live insertion events on negative supply lines, distinct from positive voltage counterparts like the LM5069.

Hot Swap Controllers Replacement Considerations

Direct substitutes include other LM5068 variants with different packaging or thermal ratings. Verify pin compatibility and electrical specifications against datasheets before replacing. Generic hot swap controllers may lack the specific automatic retry feature inherent to the '-2' suffix variant.
