ADM1272 High Voltage Positive Hot Swap Controller and Digital Power Monitor

The ADM1272 is a hot swap controller that allows a circuit board to be removed from or inserted into a live backplane. It also features current, voltage, and power readback via an integrated 12-bit analog-to-digital converter (ADC), accessed using a PMBus™ interface. This device is able to withstand up to 120 V, which makes it very robust in surviving surges.
