LT4356CMS-3#PBF - Surge Stopper from Linear Technology

The LT4356CMS-3#PBF is a robust surge stopper device designed to protect sensitive electronic circuits from high voltage transients and surges. Manufactured by Linear Technology, now part of Analog Devices, this component is engineered to shield against a wide range of power supply irregularities such as overvoltage, undervoltage, and reverse voltage, making it an essential safeguard for your electronics.

Key features of the LT4356CMS-3#PBF include its ability to regulate output during an overvoltage event, such as a load dump in automotive environments, by controlling the gate of an external N-channel MOSFET. The device operates over a wide voltage range, accommodating supplies from 4V to 80V, and is capable of withstanding transients up to 100V.

One of the standout functionalities of the LT4356CMS-3#PBF is its adjustable overvoltage and undervoltage threshold levels, which can be set with precision using external resistors. This flexibility allows designers to tailor the protection to the specific needs of their application. The surge stopper also features a fault output to indicate when the input voltage is out of the predefined safe window, providing an additional layer of system monitoring.

In the event of a fault condition, the LT4356CMS-3#PBF responds quickly, limiting the output power to a safe level by controlling the gate voltage of the external MOSFET. This rapid response helps to prevent damage to downstream components and ensures continued operation of the system.

Designed for harsh environments, the LT4356CMS-3#PBF is offered in a robust MSOP-10 package and is specified over the full industrial temperature range, making it suitable for automotive, industrial, avionics, and many other applications that require rigorous voltage protection.

With its combination of features, the LT4356CMS-3#PBF surge stopper from Linear Technology provides a comprehensive solution for protecting electronics from voltage-related damage, ensuring reliability and longevity of the systems it is integrated into.
