The ADM1276-3ACPZ is a hot swap controller designed by Analog Devices that enables circuit boards to be safely inserted into or removed from live backplanes. This device integrates digital power and energy monitoring features, accessible via a PMBus interface. It supports supply voltages ranging from 2 V to 20 V and provides a fast 370 ns response time to short circuits.
The controller features a 12-bit ADC for accurate current and voltage readback, with ±1% accuracy. The current limit is resistor-programmable from 5 mV to 25 mV. For enhanced protection, it includes foldback for tighter FET SOA protection, automatic retry or latch-off on current faults, and a programmable current-limit timer. The ADM1276-3ACPZ is housed in a 20-lead LFCSP-WQ package and is designed for surface mounting.
Applications for this hot swap controller include power monitoring and control, power budgeting, central office equipment, telecommunication and data communication equipment, and PCs/servers. Its robust feature set makes it suitable for demanding power management tasks in various electronic systems.
