Product Overview: LTC4224IDDB-1#TRMPBF

The LTC4224IDDB-1#TRMPBF is a high-performance Hot Swap™ controller IC designed by Linear Technology, now part of Analog Devices. This compact, dual-channel controller is engineered to protect low power boards and backplanes from both high inrush currents and overcurrent faults when inserting or removing boards from live backplane systems.

Key Features

• Compact Dual Hot Swap Control: The LTC4224IDDB-1#TRMPBF can independently control the power supply for two separate channels, making it a versatile solution for managing multiple power rails within a system.
• Wide Operating Voltage Range: It operates over a broad voltage range from 2.9V to 29V, accommodating various applications and ensuring compatibility with a range of power supplies.
• Adjustable Current Limit: Users can set the overcurrent limit threshold through an external resistor, providing flexibility to match the requirements of different loads.
• Fast Overcurrent Fault Response: The device features a fast response to overcurrent faults, helping to protect the circuit by quickly disconnecting the faulty channel.
• Power Good Outputs: Each channel has its own 'power good' output indicator, which can be used for downstream load enable, fault signaling, or interfacing with a microcontroller for system monitoring.
• Low Quiescent Current: The LTC4224IDDB-1#TRMPBF boasts a low quiescent current, making it suitable for power-sensitive applications.
• Overtemperature Protection: Built-in overtemperature protection ensures that the device and connected components are safeguarded against excessive heat conditions.
