LTC4226 - Wide Operating Range Dual Hot Swap Controller

General Description

The LTC®4226 dual Hot Swap™ controller allows two power paths to be safely inserted and removed from a live backplane or powered connector.

Using N-channel pass transistors, supply voltages ranging from 4.5V to 44V are ramped up at an adjustable rate.

Key Features

  • n Allows Safe Board Insertion into Live Backplane n Selectable Current Limit and Dual-Rate Timer Accommodate Load Surges n Fast Response Limits Peak Fault Current n Wide Operating Voltage Range: 4.5V to 44V n Optional Auto-Retry or Latchoff after Overcurrent Fault n High Side Drive for External N-Channel MOSFET n Allows Parallel Power Paths for High Current.
