DESCRIPTIO  
FEATURES  
The LTC®1642A is a 16-pin Hot SwapTM controller that  
allows a board to be safely inserted and removed from a  
live backplane. Using an external N-Channel pass transis-  
tor, the board supply voltage can be ramped up at an  
adjustable rate. A high side switch driver controls the  
N-Channel gate for supply voltages ranging from 2.97V  
to 16.5V.

TheSENSEpinallowsfoldbacklimitingoftheloadcurrent,  
with circuit breaker action after an adjustable delay time.  
The delay allows the part to power-up in current limit. The  
CRWBR output can be used to trigger an SCR for crowbar  
protection of the load if the input supply exceeds an  
adjustable threshold. The RESET output can generate a  
system reset with adjustable delay when the supply volt-  
age falls below an adjustable threshold. The ON pin cycles  
the board power. The LTC1642A is available in the 16-pin  
SSOP package.
