Product Overview: LTC4351IMS#PBF

The LTC4351IMS#PBF is a high-performance, dual low voltage Hot Swap™ controller designed by Linear Technology, now part of Analog Devices, to enable safe board insertion and removal from a live backplane. This robust component is ideal for protecting systems against high inrush currents that can create voltage sags and potentially damage both connectors and sensitive electronic components.

Key Features

• Wide Operating Range: The device operates with supply voltages ranging from 2.9V to 18V, making it versatile for various applications.
• Adjustable Current Limit: Users can set the current limit threshold via an external resistor, which provides flexibility in managing inrush currents for different load requirements.
• Gate Voltage Clamp: This feature protects external N-channel MOSFETs by limiting the gate-to-source voltage, ensuring reliable operation even under extreme conditions.
• Fast Overcurrent Fault Response: The LTC4351IMS#PBF is designed to respond quickly to overcurrent conditions, protecting the circuit by turning off the MOSFETs promptly.
• Power Good Output: This output signal indicates when the output voltage is within the acceptable range, providing a reliable status indicator for system monitoring.
