FEATURES  
DESCRIPTION  
2
ATCA AdvancedMC™ Compliant  
Full Power Control for Two  
AdvancedMC™Modules  
The TPS2358 dual-slot hot-plug controller provides all  
required power interface functions for two  
AdvancedMC™  
modules.  
(Advanced  
Mezzanine  
Card)  
Independent 12-V Current Limit and Fast Trip  
12-V FET ORing for MicroTCA™  
Internal 3.3-V Current Limit  
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.
