Product Overview: LTC4226IMS-2#PBF

The LTC4226IMS-2#PBF is a high-performance, dual Hot Swap™ controller designed by Linear Technology to enable safe board insertion and removal from a live backplane. It is housed in a compact MSOP package and is engineered to manage electronic circuit power distribution in systems where dual power supplies are utilized to ensure redundancy and reliability. This controller is suitable for a wide range of applications including servers, data storage systems, and telecommunications equipment.

Key Features

• Dual Channel Operation: The LTC4226IMS-2#PBF controls two separate supply voltages simultaneously, ensuring that both power paths are managed independently for optimal system performance and safety.
• Wide Operating Voltage Range: Each channel supports an operating voltage range from 2.9V to 18V, accommodating various power supply specifications.
• Adjustable Current Limit: The device provides an adjustable overcurrent limit, which helps protect the system from excessive power draw or short-circuit conditions.
• Fast Overcurrent Fault Response: The LTC4226IMS-2#PBF reacts swiftly to overcurrent events, limiting the damage to the electronic components and the power supply.
• Cross-Conduction Prevention: This feature ensures that when one supply is being hot-swapped, there is no accidental conduction path created between the two supplies, maintaining the integrity of the power distribution system.
• Power Good Outputs: Each channel has a 'power good' output that can be used to indicate a stable and within-specification output voltage, which is crucial for system monitoring and control.

Applications

The LTC4226IMS-2#PBF is versatile and can be used in a variety of systems that require reliable power distribution and the ability to safely insert or remove circuit boards without shutting down the entire system. Its robust design and feature set make it particularly well-suited for:

• Redundant Power Supply Systems
• Server and Storage Systems
• Network Routers and Switches
• Industrial PCs and Control Equipment

With its precision control and protection features, the LTC4226IMS-2#PBF is an essential component for systems that cannot afford downtime and require seamless power management for critical operations.
