OUT and Signals RESET
n Glitch Filter Protects Against Spurious RESET Signal The LTCВ®4211 is a hot swap controller that allows a board
to be safely inserted and removed from a live backplane.
An internal high side switch driver controls the gate of an
external N-channel MOSFET for supply voltages ranging
from 2.5V to 16.5V. The LTC4211 provides soft-start and
inrush current limiting during the start-up period which
has a programmable duration. n APPLICATIONS Electronic Circuit Breaker Hot Board Insertion and Removal (Either On
Backplane or On Removable Card)
n Industrial High Side Switch/Circuit Breaker Two on-chip current limit comparators provide dual level …
