The ADM1276-3ACPZ is a hot swap controller designed by Analog Devices, enabling circuit boards to be safely inserted into or removed from live backplanes. This device manages supply voltages ranging from 2 V to 20 V, providing robust protection with a rapid 370 ns response time to short circuits.
Key features include a resistor-programmable current limit between 5 mV and 25 mV, and a 12-bit ADC with ±1% accuracy for current, VIN, and VOUT readback. The controller utilizes a PMBus fast mode compliant interface for communication. It supports charge-pump gate drive for multiple external N-channel FETs, ensuring low RDS(ON), and includes foldback protection for tighter FET SOA.
Applications for the ADM1276-3ACPZ include power monitoring and control, power budgeting, central office equipment, telecommunication and data communication systems, and PCs/servers. The device reports power and energy consumption over time and features automatic retry or latch-off on current faults, along with programmable current-limit timers and multifunction GPO outputs.
The ADM1276-3ACPZ is available in a 20-lead LFCSP package.
