DESIGN FEATURES Versatile Hot Swap Controller with
Open Circuit Detect, Foldback
Current Limiting and Much More
by Mark Belch Introduction
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 LT4254 provides a compact
and robust solution to eliminate these
hot plugging issues.
The LT4254 is designed to turn
on a boardвЂ™s supply voltage in a controlled manner, allowing the board to
be safely inserted or removed from a
live backplane having a supply voltage
from 10.8V to 36V. The device features
programmable inrush current control,
current foldback, programmable 1%
tolerance on the undervoltage and …
