Product Overview

The LT1640ALIS8#PBF is a 8-pin negative voltage Hot Swap Controller allows a board to be safely inserted and removed from a live backplane. Inrush current is limited to a programmable value by controlling the gate voltage of an external N-channel pass transistor. The pass transistor is turned off if the input voltage is less than the programmable under voltage threshold or greater than the overvoltage threshold. A programmable electronic circuit breaker protects the system against shorts. The PWRGD (LT1640AL) signal can be used to directly enable a power module. It is designed for modules with a low enable input.
  • Programmable inrush current
  • Programmable electronic circuit breaker
  • Programmable overvoltage protection
  • Programmable undervoltage lockout
  • Power good control output
