LM5050MKX-2/NOPB

Overview

The LM5050MKX-2/NOPB is an N+1 ORing controller manufactured by Texas Instruments, designed for redundant power supply applications. It operates with external N-channel MOSFETs to replace diode rectifiers in power distribution networks, reducing power loss and voltage drop. The device supports input voltages from 6V to 75V and features a low quiescent current of 355 µA. Packaged in a SOT-23-6 thin case, it includes a charge pump gate driver and fast response comparator to turn off the FET during reverse current flow. Key parameters include a 450 ns turn-off delay time.

Feature Summary

Provides N+1 redundancy control for multiple power sources
Integrates charge pump gate driver for external N-channel MOSFETs
Features fast response comparator for rapid reverse current detection

Applications

Redundant power supplies
N+1 ORing controller configurations
Power distribution networks requiring ideal diode replacement

Procurement Notes

Verify the specific suffix 'X' indicates reel packaging when ordering. Confirm the '-2' designation corresponds to the N+1 controller variant rather than the single-channel version. Ensure compatibility with external N-channel MOSFETs for proper gate drive operation. Check RoHS compliance status as detailed in official documentation.

Selection Notes

Select this component for systems requiring high-efficiency power path management using external MOSFETs instead of standard diodes. The N+1 architecture allows for seamless load sharing among multiple power sources. Consider the 6V to 75V operating range and -40°C to 125°C temperature range for environmental suitability.

Part Context

This part belongs to the LM5050 family of ORing controllers. It serves as a specialized solution for managing parallel power inputs in critical infrastructure and industrial electronics. The device simplifies the design of redundant power architectures by handling the logic and timing required for safe source switching.
