ADM1272-1ACPZ

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 12bit analogue-to-digital converter (ADC), accessed using a PMBus™ interface. This device is able to withstand upto 120V, which makes it very robust in surviving surges and transients commonly associated with high voltage systems, usually clamped using protection devices such as transient voltage suppressors (TVSs) that can often exceed 100V. The load current, ILOAD, is measured using an internal current sense amplifier that measures the voltage across a sense resistor in the power path via the SENSE+ and SENSE− pins. It is used in application such as 48V/54V systems, servers, power monitoring and control/power budgeting, central office equipment, telecommunication and data communication equipment, industrial applications etc.
