What are the key features of LT4256-1IS8#PBF?

48V hot swap controller with latch-off mode for permanent fault isolation in high-voltage systems
2-channel configuration with adjustable overcurrent threshold for flexible circuit protection
SOIC-8 package enabling straightforward PCB integration in telecom and server power supplies
Adjustable threshold allows fine-tuning of inrush current and short-circuit protection levels

What is LT4256-1IS8#PBF used for?

The LT4256-1IS8#PBF is designed for hot swap protection in 48V telecom infrastructure, server blade chassis, and industrial power distribution systems where board insertion and removal under live power must not damage downstream circuits. Its latch-off fault response permanently disconnects the load upon overcurrent detection, preventing recurring damage in unattended rack-mounted systems.

Frequently Asked Questions

What voltage rail does the LT4256-1IS8#PBF protect, and how does its latch-off mode work?

The LT4256-1IS8#PBF protects 48V power rails in telecom and server systems. In latch-off mode, when an overcurrent or short-circuit fault is detected, the controller permanently disables the power path until manually reset, preventing repeated fault cycling that could damage connected boards or wiring.

How many channels does the LT4256-1IS8#PBF control, and can the current threshold be adjusted?

The LT4256-1IS8#PBF provides 2-channel hot swap control with an adjustable overcurrent threshold set by an external resistor, allowing engineers to tailor the protection level from a few milliamps to several amps depending on the 48V load requirements and connector inrush characteristics.

For which system architectures is the LT4256-1IS8#PBF in an SOIC-8 package most appropriate?

The 8-pin SOIC package suits 48V hot swap protection in standard-density server blade backplanes, ATCA chassis, and telecom rectifier shelves where board-level hot swap protection ICs must integrate alongside connectors rated for repeated insertion cycles under 48V live power conditions.
