LM5068MM-2

Hot Swap Controllers Overview

The LM5068MM-2/NOPB is a negative voltage hot swap controller designed for -10V to -80V input ranges. It operates within an extended temperature range of -40°C to +105°C and consumes 820µA of quiescent current. Packaged in an 8-VSSOP, this single-channel device controls external N-channel MOSFETs to provide programmable load current limiting and circuit breaker functions. The component supports automatic retry start-up cycles after fault conditions.

Hot Swap Controllers Feature Summary

• Controls external N-channel MOSFETs for negative voltage hot swap applications
• Provides programmable load current limiting and circuit breaker protection
• Supports automatic retry start-up cycles following fault events

Hot Swap Controllers Applications

• Negative voltage bus protection in industrial systems
• Hot swap controllers for backplane architectures
• Circuit breaker implementation for sensitive loads

Hot Swap Controllers Procurement Notes

Verify the specific suffix (e.g., MM-2 vs MMX-2) against the datasheet to confirm package type and tape/reel specifications. Ensure the NOPB designation confirms lead-free and RoHS compliance. Cross-reference the manufacturer part number with official Texas Instruments documentation to validate pinout and electrical characteristics before procurement.

Hot Swap Controllers Selection Notes

Select this component for negative voltage applications requiring precise current limiting and circuit breaker functionality. Consider the 8-VSSOP package for space-constrained designs. Evaluate the -40°C to +105°C operating temperature range against environmental requirements. Verify that the external MOSFET selection aligns with the controller's drive capabilities and voltage ratings.

Hot Swap Controllers Part Context

This device belongs to the LM5068 family of negative voltage hot swap controllers from Texas Instruments. It shares core functionalities with variants like the LM5068MM-4/NOPB but differs in packaging or ordering suffixes. The family is designed for robust power management in systems requiring safe insertion and removal of live circuits under negative supply conditions.

Hot Swap Controllers Replacement Considerations

The LM5069MM-2/NOPB is a related hot swap controller variant. Verify compatibility regarding voltage ranges and package types when considering substitutes. Ensure that any replacement maintains the required current limiting and circuit breaker features for the specific application.
