The Analog Devices ADM1275-3ARQZ-R7 is a hot swap controller designed to allow circuit boards to be removed from or inserted into a live backplane. It also functions as a digital power monitor, providing current and voltage readback capabilities via an integrated 12-bit ADC accessible through a PMBus interface.
Key electrical specifications include a wide supply voltage range of 2.95V to 20V and a fast response time of 370ns to short circuits. The current limit is resistor-programmable from 5mV to 25mV, and the 12-bit ADC offers ±1% accuracy for current, VIN, and VOUT readback. The device supports multiple external N-channel FETs with charge-pumped gate drive for low RDS(ON).
This hot swap controller is suitable for applications such as power monitoring and control, power budgeting, central office equipment, telecommunication and data communication equipment, and PCs/servers. It features automatic retry or latch-off on current faults, programmable current limit timers, and multifunction GPOs.
The ADM1275-3ARQZ-R7 is supplied in a 20-QSOP package and is designed for surface mount applications. It operates within a temperature range of -40°C to 85°C.
