Product Overview

The LTC4211IS8#PBF is a Hot Swap Controller allows a board to be safely inserted and removed from a live backplane. An internal high side switch driver controls the gate of an external N-channel MOSFET for supply voltages ranging from 2.5 to 16.5V. The LTC4211 provides soft-start and in rush current limiting during the start-up period which has a programmable duration. Two on-chip current limit comparators provide dual level overcurrent circuit breaker protection. The slow comparator trips at VCC -50mV and activates in 20µs. The fast comparator trips at VCC -150mV and typically responds in 300ns. The FB pin monitors the output supply voltage and signals the RESET output pin. The ON pin signal turns the chip on and off and can also be used for the reset function.
  • Allows safe board insertion and removal from a live backplane
  • Programmable soft-start with inrush current limiting, no external gate capacitor required
  • Faster turn-off time because no external gate capacitor is required
  • Dual level overcurrent fault protection
  • High side drive for an external N-channel FET
  • User-programmable supply voltage power-up rate
  • FB pin monitors VOUT and signals RESET
  • Glitch filter protects against spurious RESET signal
