ADI LTC4284IUHG#TRPBF

热交换控制器，监控器1I²C，OVP，UVLO

Overview

The LTC®4284 negative voltage hot swap controller drivesexternal N-channel MOSFETs to allow a board to be safelyinserted and removed from a live backplane. The dual-gate,multi-mode drivers optimize the MOSFET safe operatingarea (SOA) for a variety of power levels. The SOAtimer limits MOSFET temperature rise for reliable protectionagainst overstresses.

Additional features respond to input UV/OV, interrupt thehost when a fault has occurred, notify when output poweris good, detect insertion of a board, turn off the MOSFETsif an external supply monitor fails to indicate power goodwithin a timeout period, and auto-reboot after a programmabledelay following a host commanded turn-off.
