LTC4213CDDBIDDB - Hot Swap Controller from Linear Technology

The LTC4213CDDBIDDB is a compact, feature-rich hot swap controller designed by Linear Technology, now part of Analog Devices, to enable safe board insertion and removal from live backplanes. This integrated circuit is housed in a small 8-lead DFN package, making it an excellent choice for space-constrained applications where board space is at a premium.

Key Features

• Soft-Start Capability: The LTC4213CDDBIDDB provides a controlled inrush current during startup through its soft-start feature, which helps prevent glitches on the power supply rail.
• Overcurrent Protection: The device includes overcurrent protection with a foldback characteristic to reduce the power dissipation in the MOSFET during overcurrent conditions.
• Automatic Retry or Latch-Off: It offers a user-selectable option between automatic retry and latch-off on fault conditions, providing flexibility in response to system overcurrent events.
• Gate Voltage Clamping: The gate voltage is clamped to protect the external N-channel MOSFET from overvoltage, ensuring reliability and longevity of the system.
• Undervoltage Lockout: The LTC4213CDDBIDDB features undervoltage lockout (UVLO) with wide hysteresis to prevent the system from operating at dangerously low voltages.

Applications

This hot swap controller is particularly suitable for a variety of applications, including:

• RAID Systems
• Network Servers
• Telecom Equipment
• Industrial Systems

Technical Specifications

The LTC4213CDDBIDDB operates over a wide range of supply voltages and is designed to handle a continuous output current up to the limit imposed by the external MOSFET. Its operation is characterized by low quiescent current, making it an energy-efficient choice for modern electronic systems.
