LTC4216IDE

LTC4216IDE Description

The LTC4216IDE is a general-purpose hot swap controller designed for applications requiring reliable and controlled power-up and power-down sequences. Manufactured by Analog Devices Inc., this hot swap controller is housed in a surface-mount package, specifically a tube, and is suitable for a wide range of electronic systems. The LTC4216IDE operates within a supply voltage range of 2.3V to 6V and draws a supply current of 1.6 mA, making it highly efficient for low-power applications. It features an Under Voltage Lock Out (UVLO) mechanism to protect against low voltage conditions, ensuring system stability and reliability.

LTC4216IDE Features

The LTC4216IDE offers several programmable features that enhance its functionality and adaptability to various applications. These features include:

• Auto Retry: Automatically attempts to re-establish power after a fault condition is cleared.
• Current Limit: Provides a programmable current limit to protect against overcurrent conditions.
• Fault Timeout: Allows for a programmable timeout period after which the controller will shut down if a fault persists.
• Latched Fault: Locks the controller in a fault state until a reset is initiated.

These features make the LTC4216IDE highly versatile and suitable for a variety of applications where precise control and protection are required. Additionally, the LTC4216IDE does not include internal switches, which can be advantageous for designs requiring external control or customization.

LTC4216IDE Applications

The LTC4216IDE is well-suited for general-purpose applications where hot swap functionality is essential. It is ideal for systems requiring reliable power management, such as:

• Data Centers: Ensuring smooth insertion and removal of server blades without disrupting power supply.
• Telecommunications Equipment: Providing controlled power-up and power-down sequences for modules and cards.
• Industrial Control Systems: Safeguarding against voltage spikes and ensuring stable power delivery to sensitive components.

The UVLO feature is particularly beneficial in environments where voltage fluctuations are common, as it prevents the device from operating under insufficient voltage conditions, thereby protecting the system from potential damage.

Conclusion of LTC4216IDE

The LTC4216IDE, despite being marked as obsolete, remains a robust and reliable hot swap controller for general-purpose applications. Its programmable features, UVLO mechanism, and efficient power management make it a valuable component for systems requiring precise control and protection. While it may be considered obsolete, its technical specifications and performance benefits still hold relevance in many modern electronic systems. For applications demanding reliable hot swap functionality and precise power management, the LTC4216IDE continues to be a viable option, offering unique advantages over similar models.
