Product Overview

The LT4250LIS8#PBF is a 8-pin negative 48V 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 current limit protects the system against shorts. After a 500µs timeout the current limit activates the electronic circuit breaker. The PWRGD signal can be used to directly enable a power module. The LT4250L is designed for modules with a low enable input.
  • Circuit breaker immunity to voltage steps and current spikes
  • Programmable inrush and short-circuit current limits
  • Programmable overvoltage protection
  • Programmable undervoltage lockout
  • Power good control output
  • Bell-core compatible on/off threshold
