Frequently Asked Questions
What input voltage range does the LM5068MM-1 support for hot swap applications?
The LM5068MM-1 operates on negative supply rails from -9.3 V to -80 V, making it suitable for -48 V telecom and networking backplane systems requiring safe hot swap board insertion.
How does the LM5068MM-1 limit inrush current during board insertion?
The device uses an external sense resistor to set an adjustable overcurrent threshold, allowing designers to limit inrush current to a safe level during the 8 ms or more controlled power-up ramp when a board is hot-inserted.
Which fault response modes are available on the LM5068MM-1?
The LM5068MM-1 supports both latch-off and automatic retry fault modes selectable via pin configuration, giving system designers flexibility in a -48 V hot swap controller across 1-channel, single MOSFET drive topology.
Is the LM5068MM-1 a suitable alternative to discrete hot swap protection circuits in -48 V telecom racks?
Yes. Integrating gate drive, current sensing, and fault protection in an 8-pin TSSOP package reduces component count by at least 5 discrete parts compared to a transistor-and-comparator approach, saving board space and improving reliability in -48 V systems.
