The Analog Devices LTC4261IGN#TRPBF is a negative voltage Hot Swap controller that enables safe insertion and removal of boards from live backplanes. It utilizes an external N-channel pass transistor and allows for adjustable inrush current and overcurrent limits to protect the pass transistor during start-up and fault conditions.
Key features include an I2C interface and an onboard 10-bit ADC for monitoring board current, voltage, and fault status. The controller supports independently adjustable inrush and overcurrent limits, controlled soft-start, and adjustable UV/OV thresholds. It offers programmable latch-off or auto-retry options after faults and alerts the host when a fault occurs.
This device is suitable for applications such as AdvancedTCA systems, telecom infrastructure, and -48V distributed power systems. It is available in a 28-lead narrow SSOP package, facilitating surface mount installation.
The LTC4261IGN#TRPBF is designed for -48V operation and provides essential power management features for robust system design.
