DESIGN FEATURES Versatile 80V Hot Swap Controllers
Drive Large MOSFETs; Improve
Accuracy and Foldback
Current Limiting
by Mark Belch
Introduction
Routine maintenance and upgrades to
high reliability computing, networking
and telecommunications systems require that new or replacement circuit
boards be inserted into a powered
48V(typical) bus. When a circuit board
is inserted into a live backplane, the
input capacitors on the board can
draw high inrush currents from the
backplane power bus as they charge.
The inrush current can permanently
damage the connector pins and board
components as well as glitch the system supply, causing other boards in
the system to reset. The new LT4256
family (LT4256-1 and LT4256-2) provides a compact and robust solution to
eliminate these hot plugging issues.
The LT4256 is designed to turn
on a boardвЂ™s supply voltage in a controlled manner, allowing the board to …
