LTC1642IGN

Hot-swappable controllers

peculiarity Adjustable undervoltage and overvoltage protection Foldback current limit Adjustable current limit timeout Protected from surges up to 33 V Drivers for single-channel NFET Automatic retries for lock-up or current failure Driver for overvoltage protection triac pry bar Adjustable reset timer Unimplemented comparative reference output 16-pin SSOP package description The LTC ® 1642 is a 16-pin hot-swappableTM controller that allows boards to be safely inserted and removed from a live backplane. Using an external N-channel MOSFET, the board's supply voltage can be sufficiently adjustable to the interest rate. The high-voltage switching driver controls the gate of the N-channel with a supply voltage higher than 2.97V. The SENSE pin allows the foldback load current to limit the circuit breaker's action with adjustable delay time. Delay allows a portion of the current to be limited. The CRWBR output can be used to trigger the triac load protection crowbar if the input power exceeds the adjustable threshold. When the supply voltage falls below an adjustable threshold, the RESET output can generate a system reset delay adjustable. The power supply of the needle cycle plate. LTC1642 is in a 16-pin SSOP package.
