ADM 1276
The ADM1276 is a hot swap controller that allows a circuit board to be removed from or inserted into a live backplane. It also features current and voltage readback via an integrated 12-bit analog-to-digital converter (ADC), accessed using a PMBus™ interface.
The load current 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. A default limit of 20 mV is set, but this limit can be adjusted, if required, using a resistor divider network from the internal reference voltage to the ISET pin.

FEATURES
• Controls supply voltages from 2 V to 20 V
• 370 ns response time to short circuit
• Resistor-programmable 5 mV to 25 mV current limit
• ±1% accurate, 12-bit ADC for current, VIN/VOUT readback
• Charge pumped gate drive for multiple external N-channel FETs
• High gate drive voltage to ensure lowest RDSON
• Foldback for tighter FET SOA protection
• Automatic retry or latch-off on current fault
• Programmable current-limit timer for SOA
• Programmable, multifunction GPO
• Power-good status output
• Analog UV and OV protection
• ENABLE pin
• Reports power and energy consumption over time
• Peak detect registers for current and voltage
• PMBus fast mode compliant interface

APPLICATIONS
• Power monitoring and control/power budgeting
• Central office equipment
• Telecommunication and data communication equipment
• PCs/servers
