Applications
The LM5066IPMHE/NOPB is used in telecommunications infrastructure, data center servers, and industrial power distribution units where boards must be hot-inserted on live 48 V or 72 V backplanes without voltage disturbances. Its I2C/PMBus interface allows centralized power management systems to read real-time voltage, current, and watt-hour consumption from each board, enabling intelligent fault detection and load balancing. The device also serves in redundant power supply units and battery-backed systems requiring precise inrush control across a wide 10 V to 80 V input range.

Frequently Asked Questions
What input voltage buses does the LM5066IPMHE/NOPB support for hot swap protection?
The LM5066IPMHE/NOPB operates across 10 V to 80 V, covering standard bus voltages including 12 V server rails, 24 V industrial buses, 48 V telecom backplanes, and 72 V battery strings, making it a versatile single-device solution across multiple platform voltages.
How does the LM5066IPMHE/NOPB report power consumption data to a system management controller?
An integrated I2C/PMBus interface transmits real-time measurements of input voltage, current, and calculated power (watts) to a baseboard management controller or microprocessor, supporting telemetry-driven power capping and predictive fault analysis at 28-pin SOIC integration density.
For a 48 V data center blade server, how does the LM5066IPMHE/NOPB limit inrush current during hot insertion?
Setting an external sense resistor and gate slew resistor lets designers program inrush current to a safe limit, typically 2 A to 10 A, during the controlled power-up ramp, preventing voltage droops on the 48 V backplane that could reset adjacent active boards.
When is the LM5066IPMHE/NOPB preferred over a simpler hot swap controller without telemetry?
It is preferred in managed systems—such as ATCA shelves or intelligent PDUs—where PMBus reporting of per-slot voltage, current, and energy consumption (in watt-hours) is required for load balancing, over-budget shutdown, or maintenance scheduling, justifying the 28-pin footprint over a simpler 8-pin device.
