A fully • Internal 3.3-V Current Limit and ORing integrated 3.3-V channel provides inrush control, • I2C™ Power Good and Fault Reporting over-current protection, and FET ORing. A 12-V • I2C™ Programmable Fault Times and Limits channel provides the same functions using external FETs and sense resistors. The 3.3-V current limit is • FET Status Bits for 3.3-V and 12-V Channels factory set to AdvancedMC™ compliant levels while • Load Current Monitors for 12-V and 3.3-V the 12-V current limit is programmed using external • 32-Pin QFN Package sense resistors. The accurate current sense comparators of the TPS2459 satisfy the narrow ATCA™ AdvancedMC™ current limit requirements.
