LTC4233IWHH#PBF

The LTC4233IWHH#PBF is a low voltage SOA (safe operating area) hot swap controller in 38 pin QFN package. It is an integrated solution for hot swap applications that allows board to be safely inserted and removed from live backplane. The device 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 withstands stresses in hot swap applications. The LTC4233 provides separate inrush current control and an 11% accurate 11.2A current limit with output dependent foldback. The current limit threshold can be adjusted dynamically using ISET pin. This hot swap controller includes current monitor output that amplifies the sense resistor voltage for ground referenced current sensing and MOSFET temperature monitor output. The device has thermal limit, overvoltage, undervoltage and power good monitoring functions.
