DESCRIPTIO  
FEATURES  
The LT®1641-1/LT1641-2 are 8-pin Hot SwapTM control-  
lers that allow a board to be safely inserted and removed  
from a live backplane. Using an external N-channel pass  
transistor, the board supply voltage can be ramped up at  
aprogrammablerate. Ahighsideswitchdrivercontrolsan  
N-channel gate for supply voltages ranging from 9V to  
80V.  
Allows Safe Board Insertion and Removal from a  
Live Backplane  
Controls Supply Voltage from 9V to 80V  
Programmable Analog Foldback Current Limiting  
High Side Drive for an External N-Channel  
Latched Operation Mode (LT1641-1)  
Automatic Retry (LT1641-2)  
User Programmable Supply Voltage Power-Up Rate  
Undervoltage Lockout  
Overvoltage Protection  
Both are available in 8-Lead SO Package  
The chips feature a programmable analog foldback cur-  
rent limit circuit. If the chips remain in current limit for  
more than a programmable time, the N-channel pass  
transistor is either latched off (LT1641-1) or is set to  
automatically restart after a time-out delay (LT1641-2).  
U
APPLICATIO S  
The PWRGD output indicates when the output voltage,  
sensed by the FB pin, is within tolerance. The ON pin  
provides programmable undervoltage lockout.  
Hot Board Insertion  
Electronic Circuit Breaker  
Industrial High Side Switch/Circuit Breaker  
24V/48V Industrial/Alarm Systems  
The LT1641-1/LT1641-2 are available in the 8-lead SO  
package.
