LTC1643ALIGN#PBF - Hot Swap Controller from Linear Technology

The LTC1643ALIGN#PBF is a sophisticated hot swap controller designed by Linear Technology, now part of Analog Devices, to ensure safe board insertion and removal from a live backplane. This device allows a board to be safely inserted and removed from a live backplane without causing any disruption to the main power supply or other cards within the system. It is especially useful in high-availability systems where continuous operation is critical, such as servers, telecom equipment, and data storage applications.

Featuring an adjustable overcurrent threshold and circuit breaker functionality, the LTC1643ALIGN#PBF provides precise control over the inrush current during the hot-swap event, thereby protecting the connectors, backplane, and power supply from the potentially damaging effects of a sudden surge in current. The product integrates a 12-bit ADC for monitoring voltage and current, which aids in proactive system management and diagnostics.

One of the key attributes of the LTC1643ALIGN#PBF is its ability to operate over a wide voltage range, typically from 2.7V to 16.5V, making it suitable for a variety of applications. Its package is a 28-lead SSOP, which provides a compact footprint for space-constrained designs.

The device also includes a range of protective features, such as an adjustable timer for overcurrent auto-retry, undervoltage and overvoltage lockout, and power good status outputs. These features enhance the overall reliability and robustness of the system in which the LTC1643ALIGN#PBF is deployed.

For ease of integration, the LTC1643ALIGN#PBF offers a user-friendly interface and requires minimal external components, which can help reduce the overall design complexity and time-to-market for products utilizing this hot swap controller.

In summary, the LTC1643ALIGN#PBF from Linear Technology is a high-performance hot swap controller that provides advanced features for managing power and protecting electronic systems during hot insertion and removal. Its wide range of protective features and monitoring capabilities make it an ideal choice for critical applications where system uptime and reliability are of utmost importance.
