LTC4216IMS - Hot Swap Controller from Linear Technology

The LTC4216IMS is a sophisticated hot swap controller designed by Linear Technology, which enables safe board insertion and removal from a live backplane. This compact integrated circuit (IC) is housed in an MSOP package and is specifically tailored to manage the inrush current associated with connecting loads to a power supply, thereby preventing damage to both the connector and the system's power supply rails.

Key Features:

• Integrated MOSFET: The LTC4216IMS incorporates an internal 0.5Ω N-channel MOSFET, allowing for a streamlined design with fewer external components required.
• Adjustable Current Limit: It offers an adjustable overcurrent limit, which can be set via an external resistor. This ensures that the device can be tailored to the specific requirements of the application it is used in.
• Overcurrent Fault Timer: An onboard timer provides an adjustable overcurrent fault timeout, which helps in protecting the power source and the load during prolonged overcurrent conditions.
• Undervoltage & Overvoltage Protection: The LTC4216IMS provides both undervoltage and overvoltage protection, safeguarding the connected devices against unexpected power supply deviations.
• Power Good Output: A "power good" output signal is available to indicate when the output voltage is within the acceptable range, which can be used to enable downstream converters or alert system monitoring circuits.

Applications:

The LTC4216IMS is highly versatile and can be employed in a variety of applications, including:

• Network servers
• Storage systems
• Telecommunications equipment
• Industrial systems
• Redundant power supplies

Reliability & Performance:

Linear Technology ensures that the LTC4216IMS is built to the highest standards, offering reliable performance even in demanding environments. Its robust design is capable of handling the rapid changes in load conditions, which are common in high-availability systems. With its precision control and protection features, the LTC4216IMS is an essential component for hot swap applications that require both safety and efficiency.
