Product Overview

The LTC4234CWHH#PBF is a Hot Swap Controller that allows a board to be safely inserted and removed from a live backplane. The part integrates a Hot Swap controller, power MOSFET and current sense resistor in a single package for small form factor applications. The MOSFET Safe Operating Area is production tested and guaranteed for the stresses in Hot Swap applications. The LTC4234 provides separate inrush current control and an 11% accurate 22.5A current limit with output dependent foldback. The current limit threshold can be adjusted dynamically using the ISET pin. Additional features include a current monitor output that amplifies the sense resistor voltage for ground referenced current sensing and a MOSFET temperature monitor output. Thermal limit, overvoltage, under voltage and power good monitoring are also provided.
  • 4mR MOSFET including RSENSE
  • Current and temperature monitor outputs
  • Overtemperature protection
  • Adjustable current limit timer before fault
  • Power good and fault outputs
  • Adjustable inrush current control
  • 2.5% Accurate undervoltage and overvoltage protection
