The LTC4263IDE-1#PBF from Linear Technology is a sophisticated negative voltage hot swap controller designed to enable safe board insertion and extraction from live backplanes. This high-performance IC is engineered to control the power supply gate voltage for a smooth turn-on, thereby minimizing the inrush current and preventing the system from malfunctioning due to abrupt voltage fluctuations.

Key Features

• Advanced Hot Swap Functionality: The LTC4263IDE-1#PBF allows electronic circuit boards to be inserted into a live backplane without causing damage or disruption to the existing system.
• Integrated MOSFET Control: With an internal charge pump to control the gate of an external N-channel MOSFET, this device ensures a controlled V<sub>EE ramp-up rate.
• Adjustable Current Limit: Users can set the current limit threshold via an external resistor, providing flexibility for various application requirements.
• Overcurrent Fault Timer: An adjustable fault timer provides an additional layer of protection by responding to overcurrent conditions after a certain delay, preventing nuisance trips.
• Power Good Output: The presence of a 'power good' output signal offers a convenient way to monitor the health of the power supply.
• Wide Operating Voltage Range: Designed to work effectively over a broad range of negative supply voltages, typically from -9V to -80V.
• Robust Thermal Performance: The LTC4263IDE-1#PBF comes in a thermally enhanced 12-lead DFN package, ensuring reliable operation even in environments with high thermal demands.
