ADM1075, ADM1272, ADM1275, ADM1276, ADM1278, ADM1281, ADM1293, and ADM1294 are hot-swap
controllers that allow a circuit board to be removed from or inserted into
a live backplane. They also feature current and voltage readback via an
integrated 12 bit analog-to-digital converter (ADC), accessed using a
PMBus interface.
