The LTC4281IUFD#TRPBF from Analog Devices is a hot swap controller that enables safe insertion and removal of boards from live backplanes. It utilizes an external N-channel pass transistor to control board supply voltage and inrush current, allowing for adjustable ramp-up rates.
Key features include an I2C interface and an onboard ADC for monitoring board current, voltage, power, and fault status. The device offers analog foldback current limiting to maintain constant MOSFET power and supports a wide operating voltage range from 2.9V to 33V. It is well-suited for high-power applications due to its precise monitoring and accurate current limiting capabilities.
The controller is housed in a 28-QFN (4x5mm) package and is surface-mountable. It provides overvoltage (OVP) and undervoltage (UVLO) protection, along with programmable current limits with 2% accuracy. The device also features continuous MOSFET health monitoring, stores minimum and maximum measurements, and can generate alerts when alarm thresholds are exceeded.
Applications include enterprise servers, data storage systems, network routers and switches, base stations, and platform management. The LTC4281IUFD#TRPBF is AEC-Q100 qualified for automotive applications.
