LTC1642CGN#TRPBF - Hot Swap Controller from Linear Technology

The LTC1642CGN#TRPBF is a state-of-the-art Hot Swap controller designed by Linear Technology to enable safe board insertion and removal from a live backplane. This integrated circuit (IC) is housed in a narrow 16-lead SSOP package and is part of the Linear Technology's extensive family of power management solutions.

Featuring a wide operating voltage range of 1.2V to 16.5V, the LTC1642CGN#TRPBF is versatile and can be used in various applications, including low voltage and high voltage systems. Its primary function is to control the inrush current during system hot-swapping, thereby preventing glitches on the supply rail, connector damage, and system reset.

The LTC1642CGN#TRPBF incorporates an electronic circuit breaker to protect against overcurrent conditions. It achieves this by monitoring the voltage drop across an external sense resistor and responding to overcurrent events by quickly turning off the external N-channel MOSFET to prevent damage to the electronic components.

One of the key features of this product is its adjustable overcurrent trip level, which allows users to set the current limit according to the specific needs of their application. Additionally, the IC offers an adjustable timer for controlling the circuit breaker's response time, providing further customization to ensure system stability and reliability.

The LTC1642CGN#TRPBF also includes under voltage and overvoltage lockout capabilities, which ensure that the voltage on the board remains within safe operating levels. These features help to safeguard the system against conditions that could lead to premature failure of electronic components.

Linear Technology has designed the LTC1642CGN#TRPBF with simplicity in mind, requiring minimal external components to function. This not only simplifies the design process but also helps to reduce board space and overall system cost. With its robust feature set and reliable performance, the LTC1642CGN#TRPBF is an excellent choice for system designers looking to implement hot swap functionality with confidence.

Whether used in servers, telecom equipment, or industrial systems, the LTC1642CGN#TRPBF provides a secure and efficient solution for hot swapping capabilities, ensuring seamless maintenance and upgrade operations without the need to power down the entire system.
