LM5066IPMHX/NOPB

Hot Swap Controllers Overview

The LM5066IPMHX/NOPB is a hot swap voltage controller manufactured by Texas Instruments, designed for high-voltage system power management and protection. It operates within an extended temperature range of -40°C to +125°C and utilizes an HTSSOP-28 surface-mount package. The device supports SMD/SMT installation and includes moisture sensitivity features. It belongs to the LM5066I series under the PMIC category, functioning as a dedicated controller for managing inrush current and fault conditions in high-side N-channel MOSFET applications.

Hot Swap Controllers Feature Summary

• Provides intelligent control for high-side N-channel MOSFETs with low quiescent current consumption during normal operation and fault states.
• Features nearly constant output voltage rise times through precise inrush current control mechanisms.
• Includes input undervoltage lockout with hysteresis and programmable input overvoltage protection capabilities.

Hot Swap Controllers Applications

• High-voltage system power management
• Hot swap circuit protection
• Inrush current limiting in server backplanes

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'IPMHX' against the official datasheet to confirm the industrial temperature grade and tape-and-reel packaging configuration. Ensure compatibility with the target PCB footprint for the HTSSOP-28 package. Cross-reference the manufacturer's latest product change notifications to validate component authenticity and manufacturing origin before finalizing procurement orders.

Hot Swap Controllers Selection Notes

Select this component when designing systems requiring robust hot swap capabilities with high-voltage tolerance. It is suitable for applications needing precise control over turn-on slew rates to prevent bus collapse. Consider the HTSSOP-28 package constraints and thermal dissipation requirements relative to the expected load currents and ambient operating temperatures defined in the design specifications.

Hot Swap Controllers Part Context

This part is a member of the LM5066 family of hot swap controllers from Texas Instruments. It shares functional similarities with other devices in the series but is distinguished by its specific industrial temperature rating and packaging variant. The component serves as a critical interface for protecting sensitive downstream electronics from power supply transients and short-circuit events during module insertion or system faults.
