The TPS2358 dual-slot hot-plug controller provides all required power interface functions for two AdvancedMC™ (Advanced Mezzanine Card) modules.

Two fully integrated 3.3-V channels provide inrush control, current limiting, and overload protection. The two 12-V channels use an external FET to provide the same functions, along with ORing control circuits that allow an external FET to prevent reverse current flow. 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 TPS2358 satisfy the narrow ATCA AdvancedMC™ current limit requirements.
