Description

General part information

LTC4234 Series

The LTC4234 is an integrated solution for Hot Swap™applications 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 ISETpin. 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, undervoltage and power good monitoring are also provided. For a 10A compatible version, see LTC4233.ApplicationsHigh Availability ServersSolid State DrivesIndustrial240W, 12V Systems
