The TPS2459 hot-plug controller performs all necessary power interface functions for an AdvancedMC™ (Advanced Mezzanine Card). A fully integrated 3.3-V channel provides inrush control, over-current protection, and FET ORing. A 12-V channel provides the same functions using external FETs and sense resistors. The 3.3-V current limit is factory set to AdvancedMC™ compliant levels while the 12-V current limit is programmed using external sense resistors. The accurate current sense comparators of the TPS2459 satisfy the narrow ATCA™ AdvancedMC™ current limit requirements.
