The TPS2458 AdvancedMC™ slot controller is fully compliant with the AdvancedMC™ Standard and provides the required accuracy to meet the demands of an AdvancedMC™ (Advanced Mezzanine Card) module.

The TPS2458 is an extremely flexible solution that protects both the power supply and the load by limiting the maximum current into the load and shutting off in case of a fault. If a severe fault occurs the current shuts off immediately.

Optional ORing support is inherent in the architecture and can be used in MicroTCA™, or other applications requiring ORing support.

The 3.3-V management channel is internal and requires only one external resistor for load monitoring and one external capacitor to set fault time. To comply with the AdvancedMC™ requirements, the 12-V output is disabled unless the 3.3-V Power Good signal is asserted. Load current monitors are provided for both the 12 V and 3.3 V channels. Status outputs include Power Good and Fault indicators for each channel. The TPS2458 is in a 32-pin PQFN package.
