Product Overview: LTC4223CDHD-2#TRPBF

The LTC4223CDHD-2#TRPBF is a Hot Swap™ controller integrated circuit (IC) from Linear Technology, designed to enable safe board insertion and removal from a live backplane. This sophisticated component offers dual low voltage Hot Swap control, catering to systems that require independent control of two supply rails. It is housed in a compact, 16-lead DFN (4mm x 3mm) package, making it suitable for space-constrained applications.

Key Features

• Dual Channel Operation: The LTC4223CDHD-2#TRPBF can independently control the operation of two channels, each capable of handling supply voltages from 1V to 6V. This feature is particularly beneficial for systems with multiple supply voltages that need to be managed separately.
• Adjustable Current Limit: Users can set the current limit threshold through external resistors, allowing for precise control over the maximum amount of current each channel can deliver. This helps prevent damage to the circuit in case of an overload or short-circuit condition.
• Overcurrent Fault Timer: An adjustable timer is provided to limit the duration of overcurrent events, thus enhancing the protection of the electronic system.
• Under-Voltage Lockout (UVLO): This feature ensures that the Hot Swap operation does not commence until the supply voltage reaches a safe level, thereby preventing damage due to insufficient voltage.
• Power Good Outputs: Separate 'power good' status outputs for each channel allow for easy monitoring of the system status and can be used to enable downstream converters when stable power is established.

Applications

The LTC4223CDHD-2#TRPBF is ideal for a variety of applications where dual power supply management is required, including:

• Redundant Power Supplies
• Industrial Systems
• Network Servers and Storage Systems
• Telecommunications Equipment

With its robust feature set tailored for power management and protection, the LTC4223CDHD-2#TRPBF is an excellent choice for designers looking to enhance system reliability and maintain uninterrupted operation in their electronic systems.
