FEATURES  
DESCRIPTIO  
■
Allows Safe Board Insertion and Removal  
The LTC®4211 is a Hot SwapTM controller that allows a  
board to be safely inserted and removed from a live  
backplane.Aninternalhighsideswitchdrivercontrolsthe  
gateofanexternalN-channelMOSFETforsupplyvoltages  
ranging from 2.5V to 16.5V. The LTC4211 provides soft-  
startandinrushcurrentlimitingduringthestart-upperiod  
which has a programmable duration.  
from a Live Backplane  
■
Controls Supply Voltages from 2.5V to 16.5V  
■
Programmable Soft-Start with Inrush Current  
Limiting, No External Gate Capacitor Required  
■
Faster Turn-Off Time Because No External Gate  
Capacitor is Required  
■
Dual Level Overcurrent Fault Protection  
Two on-chip current limit comparators provide dual level  
overcurrent circuit breaker protection. The slow com-  
parator trips at VCC – 50mV and activates in 20µs (or  
programmedbyanexternalfiltercapacitor, MSonly). The  
fast comparator trips at VCC – 150mV and typically  
responds in 300ns.

the RESET output pin. The ON pin signal turns the chip on  
and off and can also be used for the reset function. The  
MS package has FAULT and FILTER pins to provide  
additional functions like fault indication, autoretry or  
latch-off modes, programmable current limit response  
time and programmable overvoltage protection using an  
external Zener diode clamp.
