LTC4281CUFD#PBF Product Details
The LTC4281CUFD#PBF Hot Swap controller allows a board to be safely inserted and removed from a live backplane. Using an external N-channel pass transistor, board supply voltage and inrush current are ramped up at an adjustable rate. An I2C interface and onboard ADC allows for monitoring of board current, voltage, power, energy and fault status.
The device features analog foldback current limiting to limit the MOSFET power to a constant value. A wide input voltage operating range comfortably allows applications from 2.9V to 33V.
The LTC4281CUFD#PBF is well suited to high power applications because the precise monitoring capability and accurate current limiting reduce the extremes in which both loads and power supplies must safely operate. Non-volatile configuration allows for flexibility in the autonomous generation of alerts and response to faults.
