LTC4217CDHC-12#PBF - Hot Swap Controller from Linear Technology

The LTC4217CDHC-12#PBF is a sophisticated integrated circuit designed by Linear Technology, now part of Analog Devices, to provide safe board insertion and removal for systems with live backplanes or other hot-swap environments. This hot swap controller allows a board to be removed and inserted into a live backplane without causing glitches or disruptions to the backplane power supply rail.

Key Features

• Wide Operating Voltage Range: The device supports a broad range of operating voltages, typically from 2.9V to 26.5V, making it suitable for various applications and ensuring compatibility with multiple system voltages.
• Adjustable Overcurrent Protection: It offers an adjustable overcurrent limit, which helps protect both the hot-swappable board and the backplane from damage due to excessive current draw.
• Foldback Current Limiting: The foldback current limiting feature reduces the power dissipation in the event of a short circuit, thereby protecting the circuit from overheating and potential damage.
• Automatic Retry or Latch Off: Upon fault detection, the LTC4217 provides the option to either automatically retry power-up or latch off, giving system designers flexibility in managing fault conditions.
• Under Voltage and Overvoltage Protection: The device includes under voltage and overvoltage protection, which ensures the connected equipment operates within safe voltage levels.
• Power Good Output: A "power good" output signal is available to indicate when the output voltage is within the acceptable range, which is useful for system monitoring and sequencing.
• Compact Package: The LTC4217CDHC-12#PBF comes in a 16-lead DFN package, offering a compact solution that is suitable for space-constrained applications.

Applications

The LTC4217CDHC-12#PBF is ideal for a variety of applications where safe power control is essential. This includes servers, network routers, switches, and storage systems. It is also well-suited for industrial applications and telecommunications equipment, where reliable power management and protection are critical.

With its advanced features and robust design, the LTC4217CDHC-12#PBF hot swap controller is an essential component for system designers looking to implement hot swap capabilities with maximum safety and minimum downtime.
