TPS2358 双槽 ATCA AdvancedMC(TM) 控制器
TPS2358 描述
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. External capacitors are used to set fault times. There is one capacitor for each channel. 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
