LTC1421CG-2.5/FLOWTR - Hot Swap Controller from Linear Technology

The LTC1421CG-2.5/FLOWTR is a sophisticated hot swap controller designed by Linear Technology to provide safe board insertion and removal from a live backplane. This integrated circuit helps to prevent glitches on the power supply rail by controlling the inrush current during the insertion of electronic boards. It is an essential component for systems that require maintenance or upgrades without the need to power down the entire system, such as servers, telecommunications equipment, and data storage devices.

Key Features:

• Adjustable Supply Voltage: The LTC1421CG-2.5/FLOWTR is tailored for a 2.5V supply voltage, making it suitable for low voltage applications.
• Electronic Circuit Breaker: This device includes an electronic circuit breaker function that protects the system by limiting the output current to a safe level during overcurrent conditions.
• Programmable Current Limit: Users can set the current limit threshold according to their specific requirements, ensuring versatility across various applications.
• Adjustable Circuit Breaker Response Time: The response time of the circuit breaker can be programmed, allowing designers to balance between fast protection and avoiding nuisance trips.
• Under Voltage Lockout (UVLO): The LTC1421CG-2.5/FLOWTR features UVLO to ensure that the hot swap controller operates only when the supply voltage is within an acceptable range.
• Thermal Shutdown: In case of excessive heat, the thermal shutdown feature protects the device by turning it off when the junction temperature exceeds the preset threshold.
• Status Indicators: It includes a fault output that signals when the device is in a fault condition and a power good output to indicate when the output voltage is within regulation.

Applications:

The LTC1421CG-2.5/FLOWTR is ideal for a variety of applications that require reliable power management and protection. It is commonly used in:

• High-availability systems
• Redundant power supplies
• Network routers and switches
• Industrial systems

With its robust set of features, the LTC1421CG-2.5/FLOWTR is an excellent choice for designers looking to enhance system reliability and safety through controlled power management.
