LTC4228-2

Overview

The LTC®4228 offers ideal diode and Hot Swap™ functions for two power rails by controlling two external N-channel MOSFETs in each rail. MOSFETs acting as ideal diodes replace two high power Schottky diodes and the associated heat sinks, saving power and board area.

  • Power Path and Inrush Current Control for Redundant Supplies
  • Low Loss Replacement for Power Schottky Diodes
  • Protects Output Voltage from Input Brownouts
  • Allows Safe Hot Swapping from a Live Backplane
  • 2.9V to 18V Operating Range
  • Controls N-Channel MOSFETs
  • Limits Peak Fault Current in ≤1µs
  • Adjustable Current Limit with Circuit Breaker
  • Adjustable Current Limit Fault Delay
  • Smooth Switchover without Oscillation
