What are the key features of LM5067MW-1?

Negative rail hot swap control manages board insertion on -48 V and similar negative supply systems without interrupting other loads
Single-channel inrush current limiting via external N-channel FET allows designers to tune current ramp using a single sense resistor
Integrated fault detection and automatic retry logic protect the load and supply rail without requiring external supervisory circuitry

What is LM5067MW-1 used for?

LM5067MW-1 is used in telecom and networking equipment powered from -48 V backplane supplies where live board insertion must not cause supply rail disturbances. It is also applied in industrial control systems and server chassis management hardware to safely bring new cards online. The 14-pin SOIC package enables straightforward integration into hot-plug controller circuits.

Frequently Asked Questions

For which supply polarity is LM5067MW-1 designed, and what voltage rails does it support?

LM5067MW-1 is specifically designed for negative supply rails, commonly used in -48 V telecom backplane systems. It controls inrush current during board hot-insertion events, protecting both the load card and the shared supply from voltage droops caused by capacitor charging surges at insertion.

How does LM5067MW-1 limit inrush current in a live-insertion application?

LM5067MW-1 controls the gate of an external N-channel MOSFET connected on the negative rail, slowly ramping the FET into conduction to limit peak inrush current. The slew rate is set by a single external capacitor, allowing designers to restrict peak inrush to well below the 1 A to 5 A threshold that might otherwise trip upstream fuses or breakers.

What happens when LM5067MW-1 detects an overcurrent or short-circuit fault?

On detecting an overcurrent event, LM5067MW-1 turns off the external MOSFET within microseconds to protect the load. After a programmed retry delay, typically set by an external timing capacitor, it attempts to restart. This automatic retry cycle continues until the fault clears, preventing permanent damage to 14-pin SOIC circuit board assemblies.

In what form factor does LM5067MW-1 ship, and how many external pins does it occupy on a PCB?

LM5067MW-1 is housed in a 14-pin SOIC (small-outline) plastic package, which fits standard 1.27 mm pitch footprints. Its 14 pins accommodate gate drive, sense inputs, fault output, and timing connections, making board layout straightforward for -48 V hot-swap protection circuits in single-channel configurations.
