TPS2458RHBT

IC, HOT SWAP, SINGLE, 32QFN.

The TPS2458RHBT is a Hot Swap and ORing Controller fully compliant with the AdvancedMC™ Standard and provides the required accuracy to meet the demands of an AdvancedMC™ (advanced mezzanine card) module. It 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 3.3V 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 12V output is disabled unless the 3.3V Power Good signal is asserted. Load current monitors are provided for both the 12 and 3.3V channels. Status outputs include Power Good and Fault indicators for each channel.
