LTC4223-2 - Dual Supply Hot Swap Controller

Download the LTC4223-2 datasheet PDF. This datasheet also covers the LTC4223-1 variant, as both devices belong to the same dual supply hot swap controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The LTC®4223 positive voltage Hot SwapTM controller allows a board to be safely inserted and removed from a live AMC or MicroTCA backplane.

It controls the main 12V supply with an external N-channel MOSFET and the 3.3V auxiliary supply with an integrated switch.

Key Features

  • Allows Safe Insertion into Live AMC or MicroTCA Backplane.
  • Controls 12V Main and 3.3V Auxiliary Supplies.
  • Limits Peak Fault Current in ≤1μs.
  • Adjustable Current Limit with Circuit Breaker.
  • Integrated 0.3Ω AUX Switch.
  • High Side Current Sense.
  • Gate Drive for External N-Channel MOSFET.
  • Adjustable Response Time for Overcurrent Protection.
  • Adjustable Supply Voltage Power-Up Rate.
  • Thermal Shutdown Protection.
  • LTC4223-1: Latch Off After Fault.
