The LTC4221CGN#TRPBF is a sophisticated dual Hot Swap™ controller designed by Linear Technology to enable safe board insertion and removal from a live backplane. This integrated circuit provides independent control of two power supply rails and is housed in a compact 16-lead SSOP package, making it ideal for space-constrained applications.

Key Features

• Independent Control: Manages two separate supply voltages ranging from 2.9V to 18V, allowing for versatile power management solutions.
• Adjustable Current Limit: Offers an adjustable overcurrent threshold via an external resistor, which enables customization for various load requirements.
• Glitch Filtering: Incorporates glitch filtering to avoid nuisance trips, ensuring stable operation during momentary current spikes.
• Power Good Outputs: Features open-drain Power Good outputs for real-time monitoring of the output voltage status.
• Fast Response Time: Provides quick response to fault conditions, protecting the system effectively against overcurrent events.
• Cross-Conduction Prevention: Prevents cross-conduction with integrated back-to-back MOSFETs during turn-on and turn-off transitions.
• Thermal Shutdown: Comes with built-in thermal shutdown to protect against overheating.

Applications

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