The TPS2359 dual-slot hot-plug controllers perform all necessary power interface functions for two AdvancedMC™ (Advanced Mezzanine Card) modules.
Two fully integrated 3.3-V channels provide inrush control, over-current protection, and FET ORing. Two 12-V channels provide the same functions using external FETs and sense resistors. The 3.3-V current limits are factory set to AdvancedMC™ compliant levels and the 12-V current limits are programmed using external sense resistors. The accurate current sense comparators of the TPS2359 satisfy the narrow ATCA™ AdvancedMC™ current limit requirements.
