3-V • 32-Pin QFN Package APPLICATIONS • ATCA Carrier Boards • MicroTCA™Power Modules • AdvancedMC™ Slots • Systems Using 12-V and 3.
3-V Channels • Base Stations DESCRIPTION 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.
