The LTC4223 is a dual Hot Swap controller that meets the power requirements of the Micro Telecommunication Computing Architecture (MicroTCA) specification recently ratified by the PCI Industrial Computer Manufacturers Group (PICMG).Hot Swap Solution Meets AMC and MicroTCA Standards Design Note 437 Vladimir Ostrerov Introduction The LTC4223 monitors 12V load current by sensing The LTC 4223 is a dual Hot Swap controller that meets voltage across an external resistor and outputs a ground- the power requirements of the Micro Telecommunication referenced voltage (at the 12IMON pin) proportional to Computing Architecture (MicroTCA) specication recently the load current. It also provides separate power-good ratied by the PCI Industrial Computer Manufacturers outputs for the two supplies and a single, common fault Group (PICMG). ……
