LM5067MM-1/NOPB

Hot Swap Controllers Overview

The LM5067MM-1/NOPB is a negative hot swap and inrush current controller manufactured by Texas Instruments. It operates within a supply voltage range of -9 V to -80 V. The device features adjustable current limiting and power limiting capabilities for precise load protection. It includes programmable input under-voltage lockout (UVLO) with hysteresis and over-voltage protection (OVP). The component supports remote on/off control via an enable input and provides fault timeout functionality. It is housed in a 10-pin MSOP package and operates across a temperature range of -40°C to +125°C.

Hot Swap Controllers Feature Summary

• Provides intelligent control of external N-channel MOSFETs for negative voltage hot swap applications.
• Features adjustable current limiting and power limiting to protect loads during insertion and operation.
• Includes programmable input UVLO with hysteresis and input over-voltage protection for system robustness.

Hot Swap Controllers Applications

• Negative voltage bus insertion protection in industrial systems
• Inrush current limiting for high-capacitance loads
• Power distribution management in telecom infrastructure

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'MM' indicates the MSOP-10 package variant when ordering. Confirm that the '-1' designation aligns with the required pinout or feature set compared to other variants in the LM5067 family. Ensure compatibility with negative voltage rails up to -80V. Check RoHS compliance status through official manufacturer documentation prior to final procurement decisions.

Hot Swap Controllers Selection Notes

Select this component for applications requiring negative voltage hot swap protection. It is suitable where adjustable current and power limiting are necessary to prevent damage during board insertion. Consider the MSOP-10 package size for space-constrained designs. Ensure the external MOSFET selected can handle the maximum system voltage and current limits defined by the controller's programming resistors.

Hot Swap Controllers Part Context

This part belongs to the LM5067 series of hot swap controllers from Texas Instruments. It is designed specifically for negative voltage systems, contrasting with high-side controllers like the LM5060. The device integrates protection features typically found in discrete solutions into a single IC, simplifying design complexity for power distribution networks.

Hot Swap Controllers Replacement Considerations

LM5067MW-1/NOPB offers identical electrical specifications but utilizes a 14-SOIC package instead of the MSOP-10 form factor. Designers must verify footprint compatibility and thermal requirements when substituting between these package types.
