LTC1647-3IGN#PBF - Hot Swap Controller from Linear Technology

The LTC1647-3IGN#PBF is a sophisticated hot swap controller designed by Linear Technology to ensure safe board insertion and removal from live backplanes. This component is an integral part of power management solutions, particularly in systems where it is necessary to replace modules without powering down the entire system. The LTC1647-3IGN#PBF is tailored to manage the inrush current, thus preventing glitches on the power supply rail and protecting the electronic circuitry from potential damage.

Featuring an adjustable current limit, the LTC1647-3IGN#PBF allows for precise control over the inrush current during the hot swap event. This is achieved via an external sense resistor that sets the current limit threshold. The device also includes a timer-controlled circuit breaker function, which provides an additional layer of protection by disconnecting the load if the fault condition persists beyond a programmed time.

Another key feature of the LTC1647-3IGN#PBF is its undervoltage lockout capability, which ensures that the controller remains off until the supply voltage reaches a safe operating level. This helps to prevent malfunctions and ensures the stability of the system. The controller also has an overvoltage protection feature, which turns off the external N-channel MOSFET when the input voltage exceeds the set threshold, thereby safeguarding the downstream components.

The LTC1647-3IGN#PBF comes in a robust 16-pin SSOP package, making it suitable for dense PCB layouts. Its wide operating temperature range makes it a reliable choice for industrial and telecommunications applications where environmental conditions can be challenging. With its advanced features and robust design, the LTC1647-3IGN#PBF hot swap controller is an essential component for systems requiring hot-swap capabilities, offering protection, flexibility, and reliability.

Whether used in servers, network switches, or storage systems, the LTC1647-3IGN#PBF by Linear Technology is a top-tier solution for managing power distribution in hot-swappable environments.
